Great article! I just signed up to Quadriga because of this. Been looking for a Canadian way to buy bitcoin through bank transfer / interact. And it's a much better service fee than what I was paying.

Here is my referal link for Quadriga if anyone else signs up from this post.

Another one for the list if you are in Canada is QuickBT.

Although it only lets you buy about $100 worth of bitcoin a day, it doesn't ask for verification besides your phone number to verify your country. So it's a good way to buy annonimously.
