What is a Change of Use Permit?

A change of use permit is official authorization from a municipality allowing a property owner to change the property's intended or legal use.

Why Change of Use Permits Matter in Real Estate

Examples:

  • Redeveloping industrial space for community use



Obtaining a change of use permit helps property owners avoid fines, legal action, and operational issues.

The downtown Toronto office building located at 145 Wellington Street West — that was set to be redeveloped into a 65-storey tower — has officially been sold, leaving the fate of the planned project up in the air.

The 13-storey Class A office building constructed in 1987 — located kitty-corner from Roy Thompson Hall and just one block away from the Metro Toronto Convention Centre — was formerly owned by Toronto-based H&R REIT (TSX: HR.UN), which has made various development proposals over the years.

If The Future Of Toronto Depends On Density, Why Do We Punish Those Who Embrace It?
Landscape view of Toronto downtown in winter.

This article is authored by Carl Laffan, who provides architectural services in Toronto, specializing in office, residential, and mixed-use projects.

The City of Toronto’s recent “gentle-density” initiative, permitting multiplexes as-of-right across the city, was proposed as an inoffensive introduction of low-rise density within the single-family neighbourhoods that cover 70% of Toronto. Although well researched and widely supported, political pressure from local opposition groups ultimately imposed bedroom caps and size limits, effectively neutering the initiative. During a period when the Canada Mortgage and Housing Corporation reported we needed 150,000 new homes, multiplex permits issued since its adoption are reported to provide only 1,288: the equivalent of two high-rise towers.

It’s been over two years since plans to adaptively reuse one of Toronto's oldest purpose-built postal offices were submitted to the City. Two refusals, three revisions, and an Ontario Land Tribunal (OLT) hearing later, the project finally has the go-ahead it sought back in November 2023.

The plans for 1117 Queen Street West have remained relatively true to the applicant’s original vision: a 29-storey condo tower integrated into a former Canada Post building, known as the Postal Station C. Featuring Beaux-Arts architecture and designed by Samuel George Curry in 1902, the building has been listed on the City Heritage Register since June 1973.

More than two years after its parent company, Berkeley Events, was placed under receivership, Toronto’s Berkeley Church has been purchased by Hyde Park Homes, with the company revealing to STOREYS that they have plans to reopen the historic event venue later this year.

Built in 1871, the three-storey, brick-faced building at 315-317 Queen Street East in Corktown was initially a Wesleyan Methodist Church. In 1999, the space was converted into an event venue, used for weddings, corporate events, parties, conferences, and even some concerts (Tegan and Sara, Feist, and the Yeah Yeah Yeahs, just to name a few). The property was designated under the Ontario Heritage Act in 1997.
