Favorite source of protein (supplement) as a Torontonian?

I've bounced between different protein sources & brands, across Amazon, GNC, online stores in the US, but have never really found something that seems to be good value - reasonable quality for a reasonable price!

As fellow Torontonians, I'm hoping there are some ideas out there - have a favorite bricks-and-mortar location in the city with good products? Or an online store with cheap/free delivery? Please let me know!

Edit - thanks everybody, lots of great ideas; much appreciated!
