From humid Ontario summers to BC's warm coastal evenings, insects are a seasonal reality across Canada. We've ranked the top Canadian online suppliers of magnetic fly screens and door screens.
⟳ Updated April 2026Canada's long summers bring blackflies, mosquitoes, and midges — especially near the country's abundant lakes and forests. Magnetic fly screens offer a practical, tool-free solution that works across all standard Canadian door and window types, and stores away cleanly through the long winter months. These online suppliers deliver direct to your door across Canada.
Simple Screen Canada is the premier magnetic screen supplier for Canadian homes, offering a full range of magnetic window screens and magnetic door screens with a standout lifetime magnet replacement guarantee. Their DIY magnetic window screen comes with Phiferglass mesh — a professional-grade fiberglass screening that is noncombustible, rust-proof, and UV-stable — ideal for Canada's varied climate from humid Eastern summers to dry Western heat. Installation requires no tools, and screens are available in multiple sizes with a sample order option so you can try before committing to a full purchase.
Fly Screen Door Canada is a dedicated magnetic door screen specialist serving the Canadian market, with a focus on the hands-free, auto-close functionality that makes magnetic screens so practical in high-use doorways. Their door screens are designed for Canadian homes — covering single doors, French doors, sliding patio doors, and wide openings — with heavy-duty magnets ensuring a reliable seal after every pass-through. The Velcro attachment system requires no drilling and leaves no damage on removal, making it ideal for Canada's large rental market.
Magnetic Window Screen is a trusted Canadian magnetic screen supplier with a specialist focus on window screen solutions for Canadian homes. Their DIY magnetic window screen kits are designed to fit standard Canadian window frames with no tools required, making them accessible for homeowners and renters across the country. As a dedicated Canadian magnetic screen supplier, they offer product knowledge and sizing guidance tailored to the window types common in Canadian housing — from older wooden frames to modern aluminium casements.
Budget Screens Canada is the go-to value option for Canadian homeowners and renters seeking effective insect protection without a large outlay. Their comprehensive magnetic fly screen range covers both windows and doors at competitive price points — popular with cottage owners, renters, and first-time buyers who want to screen multiple openings without spending a fortune. UV-resistant, moisture-resistant mesh handles Canada's seasonal extremes, while precisely positioned magnets deliver reliable automatic closure without being difficult for children or pets to pass through.
Most Canadian homes benefit from both. A magnetic door screen fits your back door, side entry, or patio door and closes hands-free behind you automatically. A magnetic window screen attaches to individual windows and peels away when you need to open them fully. Together they provide complete insect protection through the Canadian summer without any drilling, tools, or permanent modifications.
Canada's insect season is intense despite being short. The main culprits are mosquitoes, blackflies, deerflies, and horseflies. In Ontario, Quebec, and British Columbia near lakes and forests, blackflies and mosquitoes are most prevalent in late May through July. Standard 18x16 fibreglass mesh stops mosquitoes, blackflies, and deerflies effectively. For very fine insects like no-see-ums in coastal BC and Atlantic Canada, a 20x20 midge mesh provides complete protection.
Yes. Canadian homes use a mix of vinyl (uPVC), aluminium, and wood window frames — all compatible with the self-adhesive magnetic strips used to attach window screens. Clean the frame with rubbing alcohol before applying the strips for maximum adhesion. The screen frame snaps magnetically onto the strip without tools and peels away cleanly to open the window.
Yes — magnetic screens are among the most renter-friendly insect solutions available in Canada. The adhesive Velcro strips remove cleanly from door and window frames without leaving marks or residue, satisfying standard lease requirements in all Canadian provinces. Condo owners appreciate that no-drill installation means no strata council approval is needed.
Standard Canadian residential exterior doors are typically 80 inches (6 ft 8 in) high by 32, 34, or 36 inches wide — the same as US standard sizing. Add approximately 1 inch each side and top for the Velcro border. For sliding patio doors, measure the full open aperture. Most Canadian suppliers stock sizes covering these standard dimensions.
Yes — sliding patio doors leading to decks, patios, and back gardens are extremely common in Canadian homes and one of the most frequent magnetic screen applications. Measure the full opening when the slider is fully retracted, not just the glass panel. Wide-format screens are available from Canadian suppliers for larger patio door openings.
Yes — and this is one of the key advantages over permanent screen installations. At the end of summer, simply peel the magnetic screen off the Velcro strips (the strips stay on the frame), fold the screen flat, and store it inside through the Canadian winter. In spring, snap the screen back onto the existing strips — installation is instant and free each year.
The Velcro strips themselves are left on the frame over winter and perform well through Canadian temperature swings. The adhesive bond may weaken slightly if the strips get very wet in freeze-thaw cycles. Check strip adhesion at the start of each season and press firmly to reseat. Replace any strips that have lifted to ensure a strong screen attachment.
Absolutely — Canadian cottages are one of the most compelling use cases for magnetic screens. Cottage country in Ontario, Quebec, BC, and the Maritimes is often near lakes and forests where mosquitoes and blackflies are at their worst. Magnetic screens provide effective protection without permanent modification to the cottage structure — important when the property is rented seasonally or owned jointly.
Yes — blackflies are larger than mosquitoes and standard 18x16 mesh stops them completely. The key factor for blackfly control is the door screen's magnetic seal quality, not mesh density. Full-length centre-seam magnets with no gaps between them ensure blackflies cannot slip through the seam when the screen closes behind you.
Yes — cats and dogs push through the centre seam and the magnets close automatically behind them. This eliminates the need for a separate pet door. Canadian pet owners particularly value this in summer when pets are moving frequently between indoor and outdoor space. Look for reinforced double-stitched mesh edges for large breeds that put more stress on the seams.
Not directly — window screens are removed over Canadian winter. But during spring and fall when outdoor temperatures are comfortable but insects are active, magnetic window screens allow natural ventilation instead of air conditioning. A well-ventilated Canadian home during a warm May or September day needs no mechanical cooling, reducing energy costs during shoulder seasons.
Fibreglass mesh is the best choice for most Canadian applications — UV-stable, durable through seasonal storage and reinstallation cycles, and resistant to the humidity common near Canadian lakes and rivers. Phiferglass (used by Simple Screen Canada) is the premium tier, adding vinyl coating for extra longevity. Avoid nylon mesh, which degrades after 1-2 seasons even in Canada's less intense UV environment.
Yes — Simple Screen Canada (simplescreen.shop) offers a lifetime magnet replacement guarantee on their magnetic window screens. This is a meaningful differentiator: it means if the magnets ever weaken (which can happen over years of seasonal installation and removal), replacement magnets are provided. No other Canadian supplier in our rankings offers this.
Yes — all major Canadian online magnetic screen suppliers deliver nationwide via Canada Post, UPS, and FedEx. Remote territories (Yukon, NWT, Nunavut) and rural addresses may have longer delivery times and potentially higher shipping costs. Most suppliers dispatch within 1-3 business days, with delivery to most Canadian provinces taking 3-7 business days.
A self-adhesive magnetic strip is pressed onto the inner face of the vinyl window frame surround. Clean with rubbing alcohol first — vinyl is smooth and non-porous, giving excellent adhesion. The rigid screen frame snaps onto the magnetic strip. To open the window, peel the screen away; to reinstall, align and snap it back. The process takes only seconds once the strip is in place.
Extremely popular in Canada's large RV and camping market. Magnetic door screens are lightweight, fold flat for storage, and install on RV door frames without permanent modification. They provide effective insect protection at campgrounds across Canada — particularly valuable in blackfly and mosquito-heavy sites in Ontario, Quebec, and BC. They can be removed and packed in seconds when breaking camp.
Yes — they are specifically designed for DIY installation with no skills or tools required. Clean the door or window frame, cut the Velcro strips to length, press firmly onto the frame, and attach the screen. Most people complete a door installation in under 15 minutes on their first attempt. Window screens are even faster once the magnetic strip is in place.
Yes — wide-format magnetic screens cover French door and bi-fold openings. Measure the full opening width when the doors are open and order accordingly. For large openings, some Canadian suppliers can advise on the best configuration. The screen splits at the centre and closes automatically, maintaining insect protection even with both door panels open.
No-see-ums — extremely fine biting midges — are present in coastal British Columbia, Nova Scotia, New Brunswick, PEI, and Newfoundland. Standard 18x16 mesh lets them through. For these regions, choose a 20x20 midge mesh. Simple Screen Canada (simplescreen.shop) offers midge mesh options for both window and door screens — essential for coastal Canadian properties where no-see-ums are active.
Yes — with preparation. Wood frames need to be painted, dry, and smooth before applying adhesive strips. If the paint is peeling or the timber is bare, prime and repaint first. Older Canadian homes with wooden double-hung windows are fully compatible once the frame surface is in good condition. The adhesive strip bonds to the painted timber and the screen snaps on magnetically.
Yes — magnetic fly screen doors are compliant with Canadian food safety regulations for many commercial food preparation environments, providing a hands-free insect barrier that allows staff movement without propping doors open. Confirm specific requirements with your provincial health authority, as standards vary between provinces and establishment types.
Monthly during peak Canadian insect season — typically May through August across most provinces, with variation by region. Machine wash cold on a gentle cycle with mild detergent, hang to dry in shade. Avoid hot water and high-heat drying, which can weaken magnets and Velcro over time. At season end, wash before storage to prevent mould during the off-season.
Simple Screen Canada (simplescreen.shop) leads for window screens — Phiferglass mesh, lifetime magnet guarantee, standard and midge mesh options. Magnetic Window Screen Canada (magneticwindowscreen.com) is a strong alternative with a specialist window screen focus and local Canadian product knowledge tailored to standard Canadian window dimensions.
Quality magnetic screens with full-length centre-seam magnets close reliably in light to moderate breezes. In exposed or windy locations — coastal BC, the Prairies — look for screens with a weighted bottom hem or additional magnets. Fly Screen Door Canada (flyscreendoor.shop) offers reinforced sealing options suited to windier Canadian locations.
Yes — wide-format magnetic screens are popular for Canadian garage workshops where ventilation is needed but blackflies and mosquitoes are unwelcome. Size the screen for the full garage door opening and use a secure top rail attachment for the wider span. Budget Screens Canada (budgetscreens.net) offers good value for large-format applications like garages and workshops.
Yes — fibreglass and Phiferglass mesh are moisture-resistant and perform well in the high-humidity environments common near Canadian lakes, rivers, and coastal areas. The magnetic strips and adhesive are also humidity-tolerant once properly bonded. Avoid nylon mesh in high-humidity cottage country environments — it degrades much faster under sustained moisture exposure.
Measure the internal width and height of the window frame opening — the space you want to cover. Most Canadian magnetic window screens can be trimmed with scissors or a utility knife, so ordering slightly larger is the safe approach. Cut to fit after ordering for a precise finish. Measure each window individually — dimensions vary in older Canadian housing stock.
Order in April or early May — before the insect season begins and before suppliers face peak demand. Ordering ahead of the rush means stock availability and faster dispatch times. If you missed the window, Canadian suppliers typically maintain stock through summer, though dispatch times may extend during peak July-August demand periods.
Canadian magnetic screen suppliers selling direct to Canadian customers price in Canadian dollars (CAD) and include applicable taxes. Confirm pricing currency before ordering — some international suppliers list in USD and ship to Canada with additional duties or customs fees. The Canadian suppliers ranked on this site serve the Canadian market directly in CAD.
There is a particular irony in the Canadian summer experience: the weather is beautiful, the lakes are warm, the evenings are long — and the mosquitoes and blackflies are absolutely relentless. From the cottage country of Ontario and Quebec to the lakeshores of British Columbia and the forests of Atlantic Canada, insects transform what should be the best months of the year into a constant battle at every open door and window. Magnetic screen doors and window screens are the simplest solution available — and in 2026, they have never been more affordable, effective, or easy to install.
This guide covers everything Canadian homeowners, cottage owners, renters, and RV enthusiasts need to know about choosing and installing magnetic screens for doors and windows. From blackfly country in northern Ontario to no-see-ums on the BC coast, from downtown Toronto condo windows to rural Saskatchewan farmhouse doors, magnetic screens offer a practical, tool-free insect solution that stores away cleanly through the long Canadian winter.
The Canadian insect season is shorter than in the United States or Australia, but it compensates in intensity. Understanding what insects you are dealing with in your specific region helps you choose the right screen type.
In Ontario and Quebec — particularly near the Canadian Shield, the Great Lakes, and the St. Lawrence River — mosquitoes and blackflies are the primary challenge from late May through early August. Blackfly season peaks in late May and early June, with mosquitoes taking over through July and August. Both insects are stopped by standard 18x16 fibreglass mesh. The priority is a reliable magnetic seal on your door screen rather than a finer mesh density.
In British Columbia, the insect situation varies dramatically by geography. The Lower Mainland and Vancouver Island deal mainly with mosquitoes near freshwater. The Interior — Okanagan, Thompson, Cariboo — faces significant mosquito and horsefly pressure in summer. Coastal BC, particularly the North Coast and Haida Gwaii, has no-see-ums that require a finer 20x20 midge mesh. Understanding which insects are active in your specific BC location guides the mesh decision.
In Atlantic Canada — Nova Scotia, New Brunswick, PEI, and Newfoundland — no-see-ums (biting midges) are common near coastal and wooded areas. Standard mesh lets them through. If you are near the coast or in wooded cottage country in Atlantic Canada, midge mesh is worth the modest additional cost.
In the Prairies — Alberta, Saskatchewan, Manitoba — mosquitoes are a serious summer issue, particularly in low-lying and lake-adjacent areas. Standard mesh handles Prairie mosquitoes effectively. The open Prairie landscape also means more wind exposure, making door screen magnet strength and edge sealing more important than in sheltered urban settings.
The most common magnetic screen door application in Canadian homes is the back door — whether a hinged door to the deck, a sliding patio door to the garden, or a side entry used by family and pets throughout the day. In all three cases, a magnetic mesh screen that closes automatically behind every person and pet eliminates the main insect entry point without any effort from the household.
For standard single doors — the most common type in Canadian homes — dimensions are typically 80 inches high by 32 to 36 inches wide. Add approximately one inch each side and top for the Velcro border overlap. Every Canadian supplier in our rankings stocks sizes covering these dimensions as standard.
For sliding patio doors — extremely popular in Canadian homes with decks, patios, and garden access — measure the full opening when the slider is fully retracted. The opening is substantially wider than the sliding panel itself, and a screen that only covers the panel width will leave gaps. Fly Screen Door Canada (flyscreendoor.shop) and Simple Screen Canada (simplescreen.shop) both offer wider format options for larger patio door openings.
The single most important quality factor for a Canadian magnetic door screen is the magnet arrangement. Full-length continuous magnets running top to bottom along the centre seam create a seal with no gaps. Cheaper screens use intermittent magnets with gaps between them — those gaps are enough for mosquitoes, and more than enough for determined blackflies, to enter. Every supplier ranked on this page uses full-length or near-full-length magnetic sealing as standard.
Canadian homes have traditionally relied on either built-in screen window channels (common in newer construction) or aluminium-framed screens that slot into window tracks. Both work reasonably well but require seasonal removal and storage, often involve awkward track-fitting, and break or warp over time. Magnetic window screens offer a modern alternative: a framed mesh panel that attaches to your window frame via self-adhesive magnetic strips and peels away in seconds to open the window.
Canadian window frames — predominantly vinyl (uPVC) in newer builds and painted timber in older homes — are both compatible with magnetic window screen installation. Vinyl frames provide an excellent adhesive surface. Timber frames need to be painted and smooth; if the paint is peeling or the timber is bare, prime and repaint before applying the adhesive strips.
The seasonal flexibility of magnetic window screens is particularly relevant to the Canadian context. Unlike built-in screen installations, magnetic window screens are removed at the end of summer, stored flat inside through winter, and snapped back onto the existing adhesive strips in spring — instant installation year after year at no additional cost. In multi-storey homes where upper-floor windows are difficult to access, this easy in-and-out seasonal management is a genuine practical benefit.
For Canadian renters and condo owners, magnetic window screens are an especially compelling option. Lease agreements in all Canadian provinces prohibit permanent modifications without landlord consent. The no-drill, no-permanent-fixture installation of magnetic screens satisfies this requirement completely. Condo strata councils that might object to visible permanent modifications are equally unconcerned about Velcro strips applied to window frames. The screens move with you when you leave.
No guide to magnetic screens in Canada would be complete without addressing cottage country — the network of lakeside, riverside, and forested recreational properties in Ontario, Quebec, BC, and elsewhere that Canadians escape to through summer. Cottages present a specific insect challenge: proximity to water means mosquitoes and blackflies in abundance, and many cottage properties have older door and window infrastructure that traditional screen installations cannot easily accommodate.
Magnetic screens are ideal for Canadian cottages for several reasons. First, they install without tools on any door or window frame regardless of age or condition (assuming the frame is reasonably smooth). Second, they do not require permanent modification to the cottage structure — important when the property is owned jointly or rented seasonally. Third, they provide a quality insect barrier in the environments where it is needed most — evening meals on the deck, morning coffee with the door open, overnight ventilation without mosquitoes.
For cottages, order door screens sized for the specific door openings (which often differ from urban standard dimensions in older properties), and window screens for bedroom windows that are left open overnight. The midge mesh option is worth considering for Ontario cottage country near Georgian Bay and Muskoka, and for any Atlantic Canada property near wooded and coastal areas.
Canadian weather creates one important installation timing consideration. Apply adhesive Velcro strips when temperatures are above 10 degrees Celsius — adhesive bonds poorly in cold conditions. In most Canadian provinces, this means waiting until May at the earliest for reliable installation. Applying on a mild May day when the frame is dry gives the adhesive time to cure before the insect season peaks.
At the end of summer — typically September in most Canadian provinces — peel the screen from the Velcro strips (the strips stay on the frame), wash it gently, allow it to dry completely, and store flat in a cupboard or under a bed. In spring, snap the screen back onto the existing strips. Over several years, check the strip adhesion annually and replace any strips that have lifted through the freeze-thaw cycle of a Canadian winter.

For door screens, Fly Screen Door Canada (flyscreendoor.shop) offers specialist door screen construction with heavy-duty magnets and reinforced stitching for high-traffic use. Magnetic Window Screen Canada (magneticwindowscreen.com) provides the most locally focused window screen expertise for Canadian frame types. Budget Screens Canada (budgetscreens.net) delivers the best value for buyers screening multiple openings on a budget — particularly useful for cottage owners covering many windows and doors simultaneously.
Canada's summers are short and precious — and spending them swatting blackflies or keeping doors shut against mosquitoes is an avoidable waste. Magnetic screen doors and window screens are the most practical, most affordable insect solution available for Canadian homes and cottages. Install in May, enjoy all summer, store in September. It is genuinely that straightforward.
