Shouldn't be long now. As long as the bill gets passed promptly. Although Vancouver is legal for the most part already. Once it's 'legalized' the regulations are looking to be more strict than they currently are but we will have to wait a few months to see what happens to be certain.
Don't forget to visit Stanley Park, it's a great place to check out and you can occasionally find a cannabis Farmers market there or a few other spots in the city.
