Have your federal riding boundaries changed?
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.”
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.
