Bringing back fish on Air Canada - a question

[trilinearmipmap]

Lately I read that Air Canada has changed its rules on shipping of pets. You can no longer bring live animals as part of your checked luggage but you have to ship it through Air Canada cargo and pay them a shipping fee. I think this is aimed at people who want to bring dogs, cats etc. after a recent fiasco where some dogs were in the cargo hold and froze to death or something like that.

For years I have brought back fish and corals from Vancouver as checked luggage in an insulated packing box and had no problems. But I have not done this in the past few months since the new rules came into effect. I used to bring back fish in a plastic bag in my carry-on luggage until the 9-11 rules about liquids on planes came into effect.

So this is a question for anybody else who has brought back live fish in checked luggage. Did Air Canada let you do this or did they stick to their "no pets in checked luggage" rule?
