There are some other some other vendors in Canada.

There is House of Tea in Toronto. They have some rare teas, beside the
regular stuff. But they are quite expensive, as far as I am concerned.

There is also Capital Tea: www.capitaltea.com
I have heard good things about them but haven't ordered from them yet.

If you are in Toronto area, Ten Ren has shops in Toronto Chinatown, as
well as in Markham, Thornhill, and some other places. But their shops
seem to be more expensive in CAnada than in the US -- even if you
account for conversion rate.

There is also some place in Kitchener that I heard good things about
but can't remember the name.
