Did you dump your refrigerator and pantry before crossing?

A non issue.

I crossed in/out of canada several times over the pat few years with full inspection of my custom conversion sprinter van on at least 3 crossings.

They don't even look inside the refrigerator, in my experience.

We stocked up for the whole trip at whole foods and didn't even know about the limitation.

Probably, similar to the "agricultural/produce inspection" entering Florida, it's pertaining to commercial vehicles full of food.
