lol, certainly it's not cavirtex, you can find the cheapest way at my reviews https://bitcointalk.org/index.php?topic=695082.0 
Btc-e: verification: unknown, process: unknown.
usually, btc-e doesn't need verification, but sometime it is must if you deposit fiat via bank wire, so I cant sure its verification and more, my apology
just buy bitcoins, it still the cheapest on cavirtex in Canada
I also think Cavirtex is cheapest in Canada. here you can compare fee between exchanges
Does Cavirtex have a limitation on the amount you can purchase? QuickBT had a limitation as it only allowed 0.2 to be purchase at a time.
I guess it's no, but i never use cavirtex since i's not bades in canada. and i think if you have usd, you can buy cheaper bitcoin on global exchange, it's very good and easy to do so both on lakebtc and bitstamp which they are bitcoin exchange indeed with no any gambling tools.
