Easy

Paddle in from Horse on a day permit through BW.  You can make canada (moose bay) in 5-6 hrs.

RABC...lets you cross into canada without going through customs.  It is a canadian document that pre-clears you through canadian ports-of-enntry.   Takes 4-6 wks to get one in mail.  It is good for 1 yr.

Q fees are paid in either 2 ways.  Pay an Ely outfitter to drop your fees in the PP box post season.  Or you go up to PP on a tow day before and pay your fees in person.   Probably more ways to do it than that.
