There was someone on another list that has had, I am sure it was Metzer, fly the birds directly to the Calgary airport. They di explain about what they need to do and what they had to bring to the airport but only a very few folks will Metzer do that for. AND I think if you ask Metzer's they will tell you no.
There isn't a vet inspector at the airport that I am aware of, which of course doesn't mean there isn't one. You need to cross at the border, before you bring livestock into Canada, that the papers are in place. Wouldn't do much good to bring in livestock and then onces it is already on the Canadian soil find out it is carrying some disease.
You can send an email to Metzer's but I bet they tell you to pick them up at the border. But that's the worst they will tell you, I mean you can still order from them you just need to drive to pick 'em up.
