No, and dry ice is no better than Ice packs.
Frozen or fresh meet, Ice packs in a styrofoam cooler will be good for a 12 hr flight.
I could be mistaken, but I think I read somewhere last year that Ontario wasn't going to allow out of province deer into Ontario to combat the spread of CWD?
I’ve crossed back into Canada from the US with frozen deer quarters in a coffin cooler and nobody cared at the border as soon as I told them I was an archery hunter and didn’t have any firearms.
