The Greater Toronto’ Areas industrial market currently has roughly 50 million square feet of space classified as “proposed,” a figure that reflects future flexibility rather than near‑term supply pressure.

In CoStar terminology, proposed industrial space refers to projects for which a developer has identified a site and stated an intention to build, but has not yet begun construction. These projects typically have some degree of planning and financial clarity, but remain subject to market conditions, financing and final entitlements.

Much of the planning risk for these projects has already been addressed relative to earlier‑stage sites, potentially allowing development timelines to shorten when demand returns. While delivery timing will continue to vary by municipality and infrastructure constraints, shorter gaps between demand signals and new supply reduce development exposure to macroeconomic and leasing risk. In this sense, the proposed pipeline leaves the GTA well-positioned to respond more quickly to the next upswing in industrial demand.

Roughly half of all proposed industrial space is located in North GTA West, a CoStar-defined submarket that has expanded materially since the onset of the policy rate hike cycle, which hampered demand for industrial space across the region. Since the second quarter of 2022, the North GTA West submarket has expanded its inventory by 16%, or just over 9 million square feet.

Third‑party logistics demand returned in 2025, accounting for over 2 million square feet of leasing in the last quarter of last year alone. Since peaking in the third quarter of 2025, the industrial vacancy rate in North GTA West has dropped by over 250 basis points.

For large occupiers, the presence of a substantial proposed supply subtly reshapes negotiation dynamics. While relocation threats from very large tenants can often be discounted, the credible prospect of purpose‑built space aligning with lease expiries introduces practical alternatives.

As construction timelines compress, occupiers may face a broader, more realistic set of relocation options, thereby strengthening their position in renewal and termination discussions.
