I went hunting for a good set of Canada-wide WMS layers and (re)discovered some great work from NRCAN on the Toporama site
Good response time but also nice cartographic quality, well, at least if you want something that’s similar to the printed topographic map you may have on your wall. Good work as usual from NRCAN and co. Anyone know what they are serving it up with?
Here is their WMS connection.
