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?

Hard to say because the details always matter.  You'll need to
consider age of the aerial imagery, how well aligned it is, etc.  We
know that there are places where OSM data is better / more recent than
CanVec and vice versa.
