Firstly, there are online sources for hard copy topo maps in Canada, such as maptown.com, canadamapsales.com, jeffstopos.com, worldofmaps.com...these can be ordered by phone or online.
Also, there are waterproof topos available for several provincial parks (in sections), including Temagami (comprising several parks), Algonquin, French River, Killarney, Missinaibe, Mississagi etc., provided by Chrismar Adventure Maps. These can often be found in outdoor stores if you don't order them. I pick mine up this way. I like to compare where sheets end for different routes.
Secondly, it is easy once you get used to it, to use free online mapping such as Caltopo, NOmap.ca, or Gmap4. There must be others. I like Caltopo.
I take 2 full topos as backups (like a Chrismar or similar), but rely on day to day navigation with a series of 8.5"x11" printed pages stapled in sequential order of our route. She has one complete set with her in the bow, I have another with me in the stern. No fumbling necessary. Both in Ziplock bags. (I know, I still haven't bought real map cases.) The large topos are folded to show our day from one side to the other (when possible), so just flip over as we go to route find. The smaller page maps might have a high detail map (in the case of islands or shorelines), along with the days (or mornings) route. If need be we open them up to flip the page, usually near midday or at days end. I generously overlap each map. Scales tend to be varied, but I make a point of showing that on the map, as well as mag north and a highlighted route. I make simple notes in the margins with distances between chosen campsites. I go over our intended route with my partner each morning; we also discuss where we are as we go along. "Do you want to explore the shoreline coming up on our left? Looks interesting on the map." "Um. No. I'd rather paddle over to check out the little island further along on the other shore, just beyond the point." We look at the larger topo for an overall view, the smaller maps for route finding. We each have a compass. This is working for us. Hope it's been helpful for you. At journey's end I stash the printed maps away somewhere, usually in canoe books. I tried but failed to post a couple of these I kept in Word to show you.
