The Canadian Topographic system is available for the entire country at both 1:250,000 and 1:50,000 scales, it takes 16 of the latter to make one of the former. The topo system also drops down to 1:20,000 in BC with a system called the TRM maps, these maps are POD (Print-on-demand) and more expensive, they do however have the added advantage of being completely up to date as well.
