I'm sure some of you know about this, but those who don't, here is a link to Garmin's Topo Canada:
http://www.garmin.com/cartography/mapSource/topoCanada.jsp
Click the link (it says TOPO Canada) in the top right corner (in the "MapSource Map Viewer" box). You can choose larger map sizes and more detail than what initially loads. These are the same maps that I use in my GPS unit. The maps have good detail, but do not show certain things like buildings.
