Manufacturing Space
Manufacturing Space for Lease and Sale - Greater Toronto Area
Manufacturing requirements are driven by specifications that most industrial listings don't advertise prominently: power supply, floor load capacity, column spacing, and clear height for overhead equipment. Finding the right building means knowing where to look - and knowing what questions to ask before stepping inside.

Manufacturing Building Specifications: What Matters and Why
Manufacturing space is the most specification-sensitive industrial use category. A building that works perfectly for warehousing may be completely unsuitable for production - not because of size or location, but because of power supply, floor load, or column placement that constrains equipment layout. These are the variables that determine fit before location and rent become relevant.
| Specification | Critical Threshold | Acceptable Minimum |
|---|---|---|
| Power Supply | 600V 3-phase, 1,200A+ | 600V 3-phase, 400A |
| Floor Load Capacity | 10,000+ PSF | 5,000 PSF |
| Clear Height | 24' - 30' | 18' - 24' |
| Column Spacing | 40' x 50' or wider | 30' x 30' |
| Drive-In Doors | Grade-level, 14'+ wide | 12' wide |
| Gas Supply | High-pressure industrial | Standard commercial |
Power Is the First Question, Not the Last
For most manufacturing operations, power supply determines whether a building is viable before any other specification. CNC machining, welding, plasma cutting, industrial HVAC, refrigeration compressors, and spray booths all have significant amperage demands. A building with 200A service cannot support a manufacturing operation that peaks at 600A - and upgrading electrical service is not a tenant improvement, it is a capital project that takes months and costs hundreds of thousands of dollars. Confirming available amperage and phase is the first question on every manufacturing search.
Older Buildings Often Work Well for Manufacturing
The assumption that newer buildings are better does not hold for manufacturing the way it does for distribution. Buildings constructed in the 1960s through 1980s were built for production - heavier floor loads, thicker slabs, and electrical infrastructure sized for industrial equipment rather than commercial occupancies. A 1975 industrial building in Etobicoke or Hamilton may have a 10,000 PSF floor load and 1,200A service where a 2015 distribution centre has 5,000 PSF and 400A. The search has to match the specification, not the vintage.
Overhead Cranes: The Clearance Problem
Manufacturing operations that use overhead bridge cranes have a specific clearance requirement that almost never appears in a listing. The hook height - the vertical distance from the floor to the highest point the hook can reach - must account for the load height, the hook block, the crane beam, and the structural clearance to the roof. A building advertised at 24-foot clear may only support an 18-foot hook height with a typical crane installation. This is a calculation that has to be done before a lease is signed, not after equipment is ordered.
Column Spacing and Equipment Layout
Column spacing determines whether production equipment can be arranged in the flow sequence the operation requires. A stamping press line, an assembly line, or a CNC cell has a physical footprint and a material flow direction. Columns that fall in the wrong position require either an equipment layout compromise or a structural modification - neither of which is simple. Wider column bays provide more layout flexibility. For manufacturing tenants evaluating multiple buildings, column placement is among the first constraints to map before floor plans are drawn.
Where GTA Manufacturing Space Concentrates
Manufacturing space in the GTA is not evenly distributed. It concentrates in markets where industrial zoning has existed for decades and where the original building stock was designed for production rather than storage. Hamilton, Etobicoke, and North York hold a disproportionate share of the region's heavy manufacturing inventory. Mississauga and Brampton have significant light and medium manufacturing alongside their distribution infrastructure.
Hamilton is the most cost-effective manufacturing market in the Golden Horseshoe. Rents sit meaningfully below GTA averages, and the building stock - including a large inventory of former steel and industrial manufacturing facilities - supports heavier uses than most Toronto-area buildings. For manufacturers that can absorb the commute from the 403 and QEW corridors, Hamilton consistently delivers the largest buildings at the lowest cost per square foot.
Etobicoke remains one of the most practical manufacturing markets within city limits. The combination of older, heavier-spec buildings, QEW and 427 highway access, and established industrial zoning keeps it relevant for mid-size manufacturers who need Toronto geography without the Scarborough premium.
Buying a Manufacturing Building
Manufacturing owner-operators who purchase their facility eliminate the risk of a landlord repricing their occupancy cost every five years - a risk that has materialized painfully for GTA industrial tenants over the past decade as rents have trended significantly upward. Ownership locks in the cost structure and converts occupancy expense into an appreciating asset.
The purchase process for manufacturing buildings is more complex than for standard distribution space. Environmental assessment - Phase I and often Phase II - is standard practice given the previous industrial uses that characterize older manufacturing stock. Zoning confirmation is critical, particularly for specialized uses like spray coating, heat treatment, or chemical handling that may require specific permitted use designations.
Harry Makkar works within Colliers International's due diligence infrastructure to coordinate environmental review, zoning analysis, and building inspection for manufacturing acquisitions - managing a process that involves more moving parts than a standard commercial transaction.
