Film stocks in TO have thinned out dramatically. Limited selection and high prices. You can try FilmPlus but suspect you'll opt for B&H. Their shipping is reasonable and they'll tell you upfront what taxes and brokerage will be on your order. The higher C$ makes it less painful, too.
The PHSC Fall Fair is coming up next month(see thread in this section) where you can get expired film cheap. It's anyone's guess, though, what will be on offer. Rarely anything fresh for sale.
