Justin Trudeau is apparently considering an "evidenced based approach" - particularly considering legislation concerning pot and prostitution.

This is in contrast to the existing government's ideology-based approach.
If you agree with Trudeau's approach, now might be a good time to email him with your comments about it and how his adopting this as a plank in the election platform would influence your voting decision.
Just my two cents...
