pinnacle's good, sharp, but fair, i d recommend betfair an odds exchange, but wait i don't know if canadians can bet there but try it, canbet for sure, aussie book, centrebet, wil hill and ladbrokes can, and do, cut down your limits but you can bet sparcely there taking advantage of the no fees credit card fast transfer, spiro's olympic is good for soccer too, premierbet is a welcome addition too, and then there are the asian guys which both acw and matahari can talk to you about in a very appreciative way, but with which i ve yet to open up and account, hope this helps.
a betting exchange is a must, either Betfair or Betdaq or both. Pointbet is safe imo, better juice then pinnacle on spreads (-105/-105 on every league) and good for betting overs when necessary. Gamebookers is good if you bet grimy leagues but it can really only be used sparingly as their juice is awfully high.
