How does the rezoning process work in Ontario?

Rezoning means asking your municipality to change the zoning classification that applies to your property, which determines what uses and structures are permitted. In Ontario, this is done through a Zoning By-law Amendment application submitted to the local municipality under the Planning Act.

Before the municipality will consider rezoning, the proposed new use must generally conform to the municipality's Official Plan. The Official Plan sets the long-range land use framework, and zoning must implement it. If your proposal conflicts with the Official Plan itself, you may first need an Official Plan Amendment, which is a separate and higher-order process.

Once you submit a Zoning By-law Amendment application, the municipality will circulate it to internal departments and external agencies, hold at least one public meeting, and consider any written submissions. Council then votes on whether to approve, modify, or refuse the amendment. The process typically takes several months, and timelines vary significantly by municipality and complexity of the proposal.

If your application is refused, or if the municipality fails to make a decision within the legislated time periods, you may appeal to the Ontario Land Tribunal. A land use planner and a lawyer experienced in planning law can be invaluable — both to prepare a strong application and to navigate the tribunal process if needed.
