Broken commercial glass & aluminum doors in Markham: we dispatch 24/7.
Markham is roughly a 40-minute run from our Mississauga shop — less if a technician is already in the area — so a truck is usually on site the same day.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
Glass and aluminum door systems we install in Markham
Most commercial glass work is one of three aluminum framing systems, and the door is chosen to suit the frame it sits in. Canuck Door Systems supplies, installs and services all of them — here is how they differ, in the order the questions usually come.
Storefront, window and curtain wall framing: the difference
Three frame families glaze most commercial elevations, and they are not interchangeable — each one carries the glass differently, spans differently and is glazed from a different side. Which one an opening needs is usually decided by the building, not by preference.

Glass & aluminum for the work Markham buildings do
The sectors that dominate Markham — technology campuses, corporate offices, light manufacturing — each ask something different of their glass and aluminum.
Technology campuses
Entrance systems, vestibules and interior glass doors that carry a lobby’s finish — and sealed-unit replacement when a fogged lite starts telling tenants the building is tired.
Light manufacturing
Plant offices put glass where supervision needs sightlines — entrance doors with vision lites, glazed office fronts facing the floor — in aluminum framing that shrugs off an industrial interior.
Retail plazas
The storefront is the shop: aluminum-framed entrances and display glazing, same-day board-up after a break-in, and replacement glass measured and set without closing the store for long.
Schools & institutions
School and campus doors take generations of traffic: aluminum entrances rebuilt rather than replaced, wired and safety glazing matched when a lite breaks, hardware swapped without losing the frame.
Condos & property management
Lobby entrances are the building’s handshake: aluminum door systems kept aligned and closing, sealed units replaced as they fog, and board-up on call for after-hours breakage.
Hotels & hospitality
Restaurants and hotels sell the view of themselves: storefront glazing and entrance doors that match the brand, repaired around service hours rather than during them.

Common questions about commercial glass & aluminum doors
How strong is storefront glass?
Tempered glass is roughly four times the strength of the same thickness of ordinary annealed glass, and when it does fail it breaks into small blunt pieces rather than shards. That is a safety property, not a security one: tempered glass still comes out of the frame. Where the concern is forced entry or holding the glass in place after impact, the answer is laminated glass — two lites bonded to a plastic interlayer — or a security film applied to the glass already in the opening.
What kind of glass is used in storefronts?
Exterior storefronts are almost always glazed with a 1″ sealed insulating unit — two lites with a spacer and an argon or air cavity — with a low-E coating on one surface and the outer lite tempered where the code requires safety glazing. Interior storefront and partition glazing is usually monolithic 6 mm (¼″) tempered. Laminated glass replaces tempered where security, sound or fragment retention matters.
What are the disadvantages of aluminum windows?
Aluminum conducts heat, so an exterior aluminum frame that is not thermally broken will lose heat and condense in a Canadian winter. That is why residential construction largely moved to vinyl — and why commercial construction did not: aluminum carries far larger areas of glass on slim sightlines, does not rust or warp, takes any anodized or powder-coat finish, and survives commercial traffic. The fix for the one real drawback is a thermally broken frame, which we specify on every exterior opening.
