Around Vancouver I have found CanVec buildings to be quite inaccurate, so i would use Yahoo there. Best to do some mapping on the ground though with your GPS so you can be sure that Yahoo is properly rectified because I know quite a few areas in my neighborhood where yahoo imagery is off by like 100m and is all warped. :( I wish google would come on board..

I'm assuming CanVec for parks would be based on official park boundaries rather than yahoo, line of site on open spaces. So parks would be better coming from CanVec. But what about buildings?
