If you have an Oregon/Colorado/Dakota unit, you can also utilize the custom map ability to load the raster images of the Canadian Government paper topos (1:50K).
The geoTiffs are available at
http://geogratis.cgdi.gc.ca/geogratis/en/product/search.do?id=10119
You can read about making custom maps at http://www.garmin.com/garmin/cms/site/us/onthetrail/custommaps#fragment-2
You will want a utility like G-Raster to break the GeoTiffs into usable JPEG tiles. See http://moagu.com/?page_id=155
You'll probably also want Google Earth (which is pretty cool in and of itself), although it isn't strictly necessary.
Sadly, you can only load a very limited number of Topos this way. I get about 20 tiles per Topo. Since the units are limited to 100 tiles, that's just 5 topos. They are very nice maps, though the resolution isn't quite as good as on most detailed US Topos. They are generally more up-to-date than US topos (the raster maps anyway).
With any luck, the Ontario Ministry of Natural Resources will make it's Ontario Base Maps available digitally someday. They are 1:10K, which beats anything I'm aware of in the U.S. See http://themnrstore.mnr.gov.on.ca/english/map.asp?tid=0&cat=3&subcat=4 for previews.
Of course, in many ways vector maps are better, but I grew up on the paper maps, and I still love the way they look, especially now that I don't actually have to carry them around.
