Electoral reform is the biggest issue we need to tackle. Without proportional representation, Canada will continue its rightward march to polarizing American style politics.
We need to keep fighting to make the Liberals and NDP choose Canada over party.
First past the post tends to produce adversarial politics, whereas proportional representation trends to produce collaborative politics.
Canada used to be better about that because we had more minority governments, but things have been moving closer to American style two party.
I completely agree that the divisiveness at a community level is also a problem, but electoral reform is a concrete thing we can advocate for that will improve this.
The majority of Canadians support proportional representation, so the barrier is getting politicians to put down short sighted self interest.
