Buying a heritage-designated home in Ontario
Doorvia Guides · June 7, 2026
Designation under the Ontario Heritage Act can restrict alterations and demolition, and permits take time.
A property can be listed on a municipal heritage register or formally designated under the Ontario Heritage Act. Designation is the stronger status: alterations affecting heritage attributes and demolition generally require municipal approval.
That is not a reason to avoid heritage homes. It is a reason to plan. Ask the municipality for the designating bylaw and the statement of significance so you know exactly which attributes are protected - often the facade, windows and rooflines rather than the interior.
Then price your renovation intentions realistically. Approvals add time, some materials must match, and certain changes will simply be refused. Grants and tax relief programs exist in some municipalities.
