To this point: a few of my friends have done RTW's, and one of the common tips I've heard is to bake in a stop back in your home for a few days, especially on the *longer* RTW's (multi-month). These were British and Canadian friends in years when a popular start-point for an RTW ticket was Thailand, so this was logistically not too difficult.

Your plan crosses back through Canada for 1 day...maybe not the worst thing in the world if you make that a few days??? I know you don't want to lose the travel vibe, and no idea if you have friends/family in the Toronto area, but a brief reset/recharge might be useful.
