Just buy a Master Card Gift Card from Shoppers Drug Mart or other similar stores. For $25 plus a $3 activation fee, you get a disposable Master Card that has $25 on it for use in the PSN.
The only issue is that PSN charges a $1 usage fee and only allows increments of $5 to be transferred, so you'll only be able to use $20 of the card.
