Just some pre-cooked but subsequently frozen food. Nothing exotic; just normal stuff you eat at home. Entry point will probably be Detroit (air) or Windsor / Detroit (car).

I've seen people walk on board AC transborders with Pizza Pizza, but obviously they eat that on the plane so they're only sort of importing food. I'm just wondering what the rules / procedures are for bringing in what basically amounts to a week's worth of frozen leftovers.

Thanks for the comments thus far! ^
