Commercial Doors across Markham

Markham’s 338,503 residents keep those buildings busy.

Broken commercial 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.
Commercial door systems we install and repair in Markham
A commercial building runs on more kinds of door than most people ever count — a glass entrance out front, hollow metal on the exits, an overhead door on shipping, an operator on the accessible route. Canuck Door Systems supplies, installs and repairs all of them with one crew and one phone number, so "commercial doors" here means the whole building, not one product.
Hollow metal vs glass-aluminum doors
The two door systems a commercial building buys most, and they solve different problems. Hollow metal is strength: a steel slab in a welded steel frame, rated where it needs to be, indifferent to abuse. Glass and aluminum is presence: daylight, visibility and a storefront a customer walks up to. Most buildings need both — the question is which opening gets which.
Fire-rated doors in Markham: the label is the system
A fire-rated door is not a heavier door — it is a listed assembly. Door, frame, hardware and any glazing are tested together, and the rating on the label only holds while all of them match it. That is why a rated opening is specified and installed as one thing, and why swapping a closer or cutting a lite into a rated door in the field is not a small change.
Planned maintenance instead of emergency calls
Most of the door failures we attend didn't start that week — a dragging closer, a fraying overhead-door cable, a slower operator. A preventative-maintenance plan puts a technician in front of every door on a schedule: hardware adjusted, springs and cables inspected, operators tested, rated doors checked to close and latch on their own. Facility managers use it to turn door repair from a dispatch problem into a line item — and the 24/7 line is still there for the failures that don't wait.
Doors for the work Markham buildings do
The sectors that dominate Markham — technology campuses, corporate offices, light manufacturing — each ask something different of their doors.
Technology campuses
Glass-aluminum entrance systems, automatic operators for barrier-free access, and repairs scheduled around tenants — an entrance off its hinges is every visitor’s first impression.
Light manufacturing
Plants take doors hard: hollow metal doors and frames for forklift and cart traffic, heavy-cycle overhead doors on shipping, and fire-rated doors on the separations between plant and office.
Retail plazas
Storefront glass-aluminum entrances, same-day glass replacement and board-up after a break-in, and rolling security shutters or grilles for the hours the lights are off.
Schools & institutions
Fire-rated doors with panic hardware on exit routes, and entrances built for thousands of openings a day — institutional buildings are where door hardware earns its grade.
Condos & property management
Parkade overhead doors, lobby entrances and suite-level fire-rated doors, plus preventative-maintenance plans that let a property manager stop dispatching one repair at a time.
Hotels & hospitality
Entrance systems that carry the front-of-house look, operable walls to divide function space, and hotel-room doors — with repairs booked around guests, not around us.

Common questions about commercial doors
What is a standard exterior commercial door size?
A 3'0" by 7'0" single leaf is the commercial standard, and most rear, service and stairwell doors in Ontario are that size. Widths run from 2'0" to 4'0" in two-inch increments and heights are usually 6'8", 7'0" or 8'0", with 4'0" by 8'0" the largest standard single leaf before the door, its hinges and its frame all become custom. Standard pairs are built from two standard leaves — 6'0" by 7'0", from a pair of 3'0" doors, is the common double door. Staying on that grid is the difference between a door that ships in days and one that joins the four-to-six-week production queue.
How can you tell if a door is impact rated?
Be careful with this phrase, because it means two different things. In the door industry an "impact door" is a double-acting door designed for vehicle traffic, and there is no single rating stamp for it — you specify panel material, thickness and hardware. In hurricane-region building codes "impact rated" is a formal wind-borne-debris certification, which is not relevant to Ontario commercial interiors and is not what these doors are. If a specification asks for an impact rating, it is worth confirming which of the two it means before anyone prices it.
What is the difference between a hollow metal door and a steel door?
In commercial work, nothing — hollow metal is what the trade calls a commercial steel door, and the two terms are used interchangeably on drawings and in quotes. A "commercial-grade" door means exactly this assembly: a steel leaf built to an ANSI/SDI level, hung in a steel frame, prepped at the factory for commercial hardware. The distinction worth making is against residential steel entry doors: those are an insulated slab in a wood or composite frame, sold as a finished unit, and they are not built for continuous traffic, commercial hardware or a fire label. They are a different product with a different price, and we supply those too — ask for the residential line rather than this one.
