The Tenant’s Window: Why 2026 Is the Best Leasing Market in Five Years

“The best time to repair the roof is when the sun is shining.”
— John F. Kennedy

Welcome to this week’s edition of Toronto Industrial Intel. For two years, occupiers across the Greater Toronto Area absorbed the headwinds — rising rents, a wave of new supply, and landlords who held the cards. The wind has shifted. By almost any measure, this is the most favourable leasing market GTA occupiers have seen in over five years. The catch is that windows like this one do not stay open forever, and the data already shows where it begins to close.

Where Rents Actually Sit

Average net asking rents have settled in the range of roughly $15 to $16 per square foot for functional 1980s- and 1990s-era product with clear heights in the 18- to 22-foot range, a meaningful correction from peaks that pushed north of $22 net not long ago, and roughly a 9% retreat from the top of the market. The GTA-wide vacancy rate eased modestly to around 4.2% in Q1 2026 from 4.5% the prior quarter, which tells you the slide has slowed without erasing the leverage tenants have gained.

The number that matters most, though, is the one that never appears on a brochure: the net effective rent. Between free-rent periods, tenant improvement allowances and turnkey delivery, the achievable economics of a deal today often sit well below the face rate. That gap is where the opportunity lives.

Why the Window Has a Shelf Life

Here is the part occupiers should not miss. The construction pipeline has fallen sharply, down roughly 50% from its 2023 peak to the lowest level of new GTA industrial space under construction since 2018. Today’s tenant leverage exists because supply outran demand. As that pipeline thins and the market digests its excess, the best space tightens first. Concessions are a function of competition among landlords; reduce the available supply and that competition fades. Acting while the window is open is not opportunism — it is timing.

Five Moves for Occupiers Right Now

1. Renew early, or blend and extend. If your lease expires in the next 12 to 24 months, you do not have to wait for the clock to run out. A blend-and-extend can capture today’s economics ahead of expiry and bank them into a longer term.
2. Go long to lock in the lows. Landlords will trade deeper concessions for term certainty. A longer commitment now secures today’s softer rents before the cycle turns.
3. Take concessions over headline cuts. Many landlords will protect the face rate but offer free rent, TI allowances and OpEx caps. Structure the deal around net effective cost, not the number on the sign.
4. Buy flexibility while it is cheap. Expansion rights, contraction options and clean sublease language are easiest to negotiate when landlords are competing for you. That flexibility is your insurance for when the market firms again.
5. Read the market submarket by submarket. Leverage is not evenly distributed, which brings us to the map.

A Submarket Cheat Sheet

Conditions across the GTA are not uniform, and our quarterly coverage has tracked the divergence. GTA West  the Peel and Halton engine  has carried the most new supply and, in pockets, the deepest concessions. GTA North has seen vacancy climb toward decade highs, putting unusual leverage in tenants’ hands in submarkets like Vaughan. GTA East has been the tighter story, with vacancy compressing and leasing surging, meaning the window there may close soonest. The takeaway: where you look matters as much as when, and the same building specification can carry very different economics depending on which side of the region it sits on.

The sun is shining on occupiers right now. The roof, so to speak, is worth repairing while it is. For tenants with a lease decision on the horizon, the most expensive choice is often to wait and watch the leverage drain away.
