Moonbeam Coffee Co in the Kensington Market - roasted fresh, 100% Kona (It's Phenomenal). I think they sell for about $25-$35 a lb. Very reasonable for the quality as I remember (i.e. you won't find it cheaper).
If you can't afford the $40 per/lb Moonbeam Kona, go for the Merchants of Green Costa Rican roast... it's organic, shade-grown and fairtrade and is the smoothest, most flavourful coffee I've had anywhere! And its only $15 per/lb.
