I seem to be the only one here actually living in Quebec and yes there's the law and even a jurisprudence as already mentionned. Fine.
Please do yourself a favor and come to Montreal and/or Quebec City !
You will enjoy 2 fantastic cities, each with its own particularities. Quebec being wayyyy better than Montreal (Small inside joke here

)
As far as the street photography goes, I must be on hundreds of pictures from tourists from anywhere in the world.
Due to my celebrity ? Nope. Due to my sexiness ? Nope again. Just because I'm there in the city where boatloads of people are taking pictures.
The people you will freeze in your photos are iether locals or other tourists like you. How on earth would those people know you, your blog, your website, etc. ?
Unless you took a picture of a person and publish it in a local ad, there's no any chance you will run in any problem.
Nous sommes friendly
