In 2023 the federal riding boundaries were redrawn, and they now no longer correspond to the provincial riding boundaries (as they formerly did).
“A redistribution of federal electoral districts (“ridings”) began in Canada following the results of the 2021 Canadian census. The Constitution of Canada requires that federal electoral districts that compose the House of Commons undergo a redistribution of boundaries following each decennial Canadian census. The redistribution process began in October 2021; it was completed in October 2023. It is based on data obtained during the 2021 Canadian census. It is also based on the practice of giving each district only one member, which has been in effect since the 1968 election.” *
There were many changes in particular to the federal electoral district boundaries within the City of Toronto, which take effect for the 2025 Canadian federal election. You can search for your district information by a number of means.
