Assuming none are CITES listed animals, all you need is a USFW inspection. Yes, you must declare them, you must have an invoice showing value so that Canada Customs can collect GST and whatever the PST is for Manitoba, as well as common and Latin names. You cannot have any more that 8 of any species without a commercial import permit. It is also helpful if you have a book with you illustrating the species you are importing.
If anything is CITES listed, forget it unless the person you are buying them from has already applied for and received export permits. The process can take months.
