Markham Warehouse Market

Markham is York Region's most established industrial submarket, with the deepest inventory concentration in the 407/404 corridor and the lowest vacancy rate among York Region municipalities. The submarket's position at the Highway 407/404 interchange — with direct 407 access to Vaughan and Pearson Airport to the west and to Ajax and Durham Region to the east — makes it one of the most logistically versatile addresses in the GTA North market. Markham's industrial stock spans a wide spectrum: Steeles Avenue East and Highway 7 East house established 1980s and 1990s-era multi-tenant industrial parks with smaller bays suited to light manufacturing and trades, while the 407/404 node has attracted newer distribution-format buildings with 30-36 foot clear heights for e-commerce, logistics, and food distribution tenants. Markham also hosts a large concentration of technology and life sciences employers in its mixed-use corridors, creating strong demand for specialized light industrial and flex space. Net asking rents in Markham range from $15.50 to $19.00 per square foot net, with newer 407-adjacent Class-A product at the upper end and older multi-tenant stock on Steeles and Highway 7 at $15.00 to $16.50. Markham is the primary York Region market for tenants who prioritize the 407 ETR east-west corridor. Michael Law advises industrial tenants and investors across York Region including Markham, Richmond Hill, Aurora, Vaughan, and the broader 407 corridor.

Sourcing Warehouses for Lease — My Approach

When I source warehouse space for a tenant, the rent number is the last thing I look at — not the first. The questions that actually drive a successful warehouse lease are: what is the building's true power capacity (often the bottleneck for racking, automation, or refrigeration), what is the trailer storage and yard depth (critical for any 3PL or distribution use), what is the clear height under the joists versus the deck (a common 2-3 foot misrepresentation in listing materials), and what does the dock-to-door ratio actually look like at peak operating volume. I walk every short-listed building with the tenant's operations lead, not just the real estate lead, because the person who actually runs the floor catches things the marketing brochure hides — slope of the slab, location of the column grid relative to racking layout, sprinkler density for the proposed commodity classification. A great warehouse lease starts with the operational fit, not the per-square-foot rent. Rent is the negotiation that comes after we've found the right building.
