There are sections of Georgian Bay, especially in the north/east which are fairly remote, even in cottage country, during the week it’s fairly isolated.
Trent Trip was a walk in the park compared to this, there was really no remote areas, Trent Waterway passes right through cottage country and at the locks each evening there are many people to socialize with. On Georgian Bay, might be days without seeing another person.
Cell Phone coverage also is extremely limited a number of areas, if something happens, options may be limited and ability to be rescued is measured in hours/days not minutes.
This is the biggest reason I would like a paddle partner on this one, if something happens then I have someone else there to deal with the situation.
Expect the best, plan for the worst!
