I recently created a community called "Toronto de Nihongo no hon ga yomitai", and it's got a few links to Japanese bookstores and libraries in Toronto. HTH

I've all but given up on ever being able to read anything beyond mixi, but I went there once. Pretty good. Bit weird. Got a lot of weird looks. Was a lot taller than everyone else there.
And yeah, Robarts has something called the east asian library on the 8th floor, I think. Once again, went there. Seemed good. Bit weird. Got a lot of weird looks. Was a lot taller than everyone else there.
They're basically the same, I think.
