*The land area figures mentioned in the table and elsewhere in the report are preliminary calculations and will be reviewed and certified after the proclamation of the Representation Order.

This plan and the accompanying report will be presented to the Chief Electoral Officer of Canada to be transmitted to the Speaker of the House of Commons for consideration.

After Parliament has considered the report in accordance with the provisions of the Electoral Boundaries Readjustment Act, it is returned to the Commission with any objections, the minutes, and evidence of the House of Commons committee. Once the objections have been addressed, a certified copy of our report shall be returned by the Chief Electoral Officer to the Speaker.

Once the Chief Electoral Officer of Canada has received the final reports of all Commissions, a representation order is prepared describing and naming the electoral districts established by all Commissions.

The Governor in Council announces the new boundaries in a proclamation published in the Canada Gazette.

New boundaries can first be used in an election if at least seven months have passed between the date that the representation order was proclaimed and the date that Parliament is dissolved for a general election.

Respectfully submitted and dated at our respective locations, in the Province of Ontario, this 8th day of February 2023.

Federal Electoral Boundaries Commission for the Province of Ontario
