Hello,
My name is Regie Alam, from Ottawa. This is my first post on the list although I've been receiving the messages for quite some time now.
I am just wondering if there is an accepted protocol for ground truthing the data (Canvec, etc.)? I would find it interesting doing some ground truthing.

Bonjour Michael
About accuracy: Canvec should usually be better than 10m (90%) for road network and 30m for other features. We know that Yahoo imagery often have offsets. However, you better have plenty of gps tracks to take a decision.
By the way, there is no park boundaries in Canvec product -for the moment.
About contents: Yahoo imagery is usually more up-to-date than Canvec - except for road network and for hydrography in some provinces.
I agree with Richard, the details always matter. You may sometime have to choose between accuracy and completeness...
