Commercial door repair and fire door inspection in Markham
Door repair, installation, maintenance and fire door compliance for Markham’s corporate, industrial and institutional buildings.
Corporate campuses, secured floor by floor
Markham’s technology and corporate sector gives the city a distinctive door profile: heavily secured buildings where nearly every opening is electrified, and where access control was designed in rather than added later.
The technology corridor
Office and research campuses along the 404 and 407, many with controlled access at every internal boundary — card readers, electric strikes, magnetic locks, door position monitoring, and often a security system that reports on doors it does not actually control mechanically.
The recurring problem in these buildings is a mismatch between what security believes about a door and what the door is actually doing. A door reporting closed can still be failing to latch. A mag lock that releases on alarm in testing can bind under real conditions if the frame has shifted. Neither shows up on a panel.
Milliken and the Steeles industrial belt
Older light industrial and warehousing along the southern edge of the city. Hollow metal throughout, well used, with the accumulation of hardware substitutions typical of stock that has turned over tenants several times.
Downtown Markham and Unionville
Newer mixed-use office and retail alongside older heritage commercial in Unionville. Two very different sets of constraints — modern specification and configuration issues in one, irreplaceable frames and heritage considerations in the other.
Retail and multi-tenant
Markville and the surrounding retail carry rated separations between tenancies and back-of-house that are easy to overlook, particularly where a unit has been fitted out several times.
Institutional Markham
Markham Stouffville Hospital, a substantial school board estate, York Region administrative facilities and several long-term care homes.
These carry the highest fire separation density in the city and documentation expectations that go beyond the Fire Code — regulators in healthcare and long-term care ask for records on their own schedule, not the fire inspector’s.

What we repair →Fire door inspection
Per-door inspection and documentation to Ontario Fire Code duties and NFPA 80 inspection criteria, photographed and recorded.
How inspections work →Installation & maintenance
New doors, frames and complete openings, plus scheduled maintenance across a portfolio.
Planned maintenance →Electromagnetically locked doors have their own requirement
On 1 January 2026 the Ontario Fire Code gained Article 2.7.2.3, and one part of it lands squarely on buildings like Markham’s. Electromagnetic locks must be tested at intervals not greater than 12 months, and under Article 2.7.2.4 the record of that test has to be made and kept. Separately, every door forming part of a means of egress is checked at intervals not greater than one month to confirm it is operable.
Doors in fire separations carry a different and much older duty: inspected monthly, under Article 2.2.3.4(4). That one is not new, and it has no exemption — the exceptions at 2.2.3.4(3) relieve a door from being held closed, not from being inspected. The two requirements are often confused. They are separate articles, separate cycles, and separate records.
The mag lock duty matters here more than almost anywhere. The Fire Code permits an electromagnetic locking device on an access to exit or an exit door only where it is approved or complies with the Building Code — Article 2.7.2.2(2). The release behaviour is set by that approval rather than by the Fire Code. What the Fire Code requires is that the lock be tested on a 12-month cycle and the result recorded. A lock that no longer does what it was approved to do is both a hazard and a failed test, and it is not something you find by looking at the door.
Markham Fire and Emergency Services enforces the Fire Code locally, and an inspection that finds doors out of compliance can result in an order with a deadline attached.
The obligation falls on the “owner”, and the Code’s definition is wider than most people expect: “any person, firm or corporation having control over any portion of the building or property under consideration”, and it expressly includes the persons in the building (Division A, Article 1.4.1.2). Article 1.2.1.1 then makes the owner responsible for carrying out the Code.
