On cavirtex there's no method of depositing CAD funds that doesn't require verification. There's multiple of ways to withdraw fiat without verification.
Which means it's harder to get fiat in to buy than getting btc in to sell + withdrawing fiat. So it's like a reverse MtGox effect. I'm trying to get verified to get these bargain prices but I don't have any utility bills to prove my address. It's somewhat annoying.
