I can easily spend 50-60$ a day or more, not including transport to start and from end. I tend to have one restaurant meal a day, usually breakfast. Campgrounds in Canada costs 25-30$. I toured in southern Ontario this spring and all campgrounds were 40$+ for crappy sites among RVs. I got sick of that and ended up staying indoors for 60-80$. I free-camp occasionally but then a couple of nights in a downtown hotel more than makes up for it. Add C-store food, ice cream, ferries, entertainment, etc, and it cost goes up quickly. It's easy to keep cost down if you want to, but when the campsite is 10-15km out of town and I'm dead tired, riding on a street lined with motels and restaurants, that extra 10km is just too much.
