Toronto is an office construction hotbed, with 5M SF under development across the GTA, much of it AAA space. Here—via fresh figures from the folks at Colliers—are four submarkets that are bustling right now.

1. Financial Core

Development: Nearly 2M SF under construction, all of it AAA space, like Oxford’s EY Tower. The core is TO's most active submarket by far on the development front.

Vacancy: A mere 2.6% last quarter, up from 2.2% in Q1.

What’s available: Availability rate is 9.4%, and there’s 3.4M SF of available space. Net absorption in Q2 was 9.5k SF.

2. Downtown South

Development: 800k SF under construction, including Menkes Developments' One York Street (Downtown East isn't far behind, with 749k SF being built).

Vacancy: Nearly nonexistent, at 1.7%, down from 6.7% in Q1, likely due to the 288k SF absorbed last quarter.

What’s available: Availability rate is 3%, and there's 170k SF of available space. Net absorption in Q2 was 284k SF.
