National Resources Canada has recently updated their Toporama online topographical viewing software. You can now get topographical maps for all of Canada with scales as low as 1:40,000 for free. It’s still a pain in the ass to have to copy and past all the sections together if you want a get a usuable trail map, but the maps are far better than what Garmin Topo Canada provides. All the trails and most of the campsites for the major National Parks seem to also be marked on the Toporama maps.

Now if only you could download the full maps like USGS allows in the states…

Update:
After reading the License Agreement for Digital Topographical Data it looks like there is no reason I can’t post a copy of the Yoho National Park topographical trailmap I put together.

So here it is:
Yoho National Park of Canada - Free Downloadable Topograpical Trail Map - Scale 1:40,000 (hint hint Google…)

Update 2:
Might as well post one for Kootenay National Park aswell.
