Cobourg is in the Riding Northumberland-Peterborough South which was formed after a re-distribution in 2012. See below for more on re-distribution.
Northumberland-Peterborough South
In 2021, incumbent Conservative M.P. Philip Lawrence won with a big majority although Liberals were returned nationally with a minority Government. The next scheduled election will be in 2025 although with a minority in the House, an earlier election is possible.
Redistribution
Before the next election, the boundaries will be changed (unless the election is before April 2024 - for a time line, go here.). The first suggestion made for a new boundary excludes Peterborough but adds Milbrook. Roseneath and Alderville will not be included. The new Riding will be called Northumberland and will in fact mostly be Northumberland. For a before and after map, go here. The new Riding will also be used for the Provincial Election scheduled for 2026.
