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.
In my experience online purchase limits depend entirely upon the level of verification and KYC/AML BS you are prepared to put up with
