I've been using vault of satoshi for a few months. The volume is a bit low, but it's the only cryptocurrency exchange that I trust. BTC-e is a blackbox and there are allegations that they selectively rip off clients. VoS has a real office in Ontario with real support. They conduct pretty in-depth AML (over compliant with PCMLTF imo) as well. It supports a lot of different cryptocurrencies, support is super fast, you can see proof of its holdings, you can visit their office and their fees are much more reasonable than Cavirtex. In short, if you live in Canada, VoS is your best (read, safest) choice.
