Wow... I forgot about this thread - thanks for digging it up!
I went with FIDO, I live at Bay / Wellesley, and on my Nokia 6100 I get full coverage between home and Pearson (via the Gardiner and 427).
For me, as I am on a 2 year contract (unlimited fido 2 fido in Canada for $25, with free evenings/weekends, 150 minutes anytime), I get it free.
