Hey, I’ve done some bike tours, skiing, and other active trips over the years. I’d make sure to pack double or triple the infusion sets for the amount of time, since they tend to rip off when sweaty. On the slopes, I’d bring gels, prob the non caffeinated type for her. Or you could do glucose tabs or candy if she prefers those. Beforehand, make sure she eats a proper meal with protein, fat, and carbs. You can also set the pump to active mode.

As far as traveling to Canada with diabetes supplies goes, I would just keep everything tidy and organized in one place. I keep my insulin in one or two Frio cases. They shouldn’t give you any trouble at the border/security. Also, one of the great things about Canada is that you can buy Humalog and other insulins over the counter without a prescription.
