canadian here as well. i picked up ginger tablets at our local costco. i believe they have them at most pharmacies. i could not find bonnin here in canada and did not want to take the chance of having nothing. i had also seen some threads that said it made you drowsie and i don't want that either.
i watched an eposode of myth busters a few months back on sea sickness remedies and ginger tablets was the one voted to work best without you getting drowsy. you may want to try this.
We're another Canadian family!!

I heard about the ginger pills, but not sure if they're good for the kids!?!
