What is a Builder Permit?

A building permit is an official approval issued by a local municipality that authorizes a property owner to construct, alter, or demolish a building or structure.

Why Builder Permits Matter in Real Estate

In Canadian real estate, building permits are crucial for ensuring that construction and renovations are carried out in accordance with safety regulations, zoning bylaws, and provincial building codes.

Permits are generally required for:
  • New home construction
  • Additions or structural changes
  • Major interior renovations (e.g., moving walls, installing new plumbing or electrical systems)
  • Building garages, decks, sheds, or fences (depending on local bylaws)
The permit process typically involves submitting architectural plans, waiting for municipal review and approval, and completing inspections at key stages of the project.

Failing to obtain a permit can lead to stop-work orders, legal penalties, problems during resale, and forced removal of unapproved structures.
Understanding building permits helps property owners stay compliant, ensure safety, and preserve property value. Always check with the local municipality to determine permit requirements before starting any major work.

Example of a Builder Permit

A homeowner in Calgary applies for a building permit before converting their garage into a home office, triggering plan reviews and city inspections.

Key Takeaways

- Required for most major construction or alteration.

  • Ensures work complies with codes and zoning.
  • Must be obtained before starting the project.
  • Involves inspections at key milestones.
  • Protects legal and resale value of property.

Ontario’s Trust Test: Lessons From The iPro Realty Collapse

Ontario’s Trust Test: Lessons From The iPro Realty Collapse
iPro Reality branch in Brampton, Ontario/Google Maps

This article was written and submitted by former CEO of the Ontario Real Estate Association (OREA) Tim Hudak and long-time senior Ontario civil servant Frank Denton. Hudak is currently partner at Counsel Public Affairs Inc., and Denton is a senior advisor.

The collapse of iPro Realty, one of Ontario’s largest independent brokerages, has left at least an $8-million shortfall in its trust accounts and put the regulator, the Real Estate Council of Ontario (RECO), under an intense spotlight. For buyers, sellers, and real estate agents, the scandal raises urgent questions about whether their deposits are safe. When suspicion falls on an arm’s-length regulator with delegated authority from government, pressure on the Minister to act is swift. At its core, this is not just a regulatory challenge but a trust challenge — and once public trust is broken, other delegated authorities in Ontario may soon be under the same spotlight.

Despite the fact that Toronto’s unhoused population has more than doubled since 2021, the City is set to receive a fraction of the Canada-Ontario Housing Benefit (COHB) funding in its sixth year that it did in both its fourth- and fifth-year allocations.

Toronto Mayor Olivia Chow wrote in a letter that went to the Executive Committee on Monday that the Province allocated $38 million to Toronto from the COHB between April 2024 and March 2025, and $19.75 million from April 2025 to March 2026 — but between April 2026 and March 2027, the City will receive only $7.95 million, representing an almost 60% decrease year over year.
