Well, I thought my Namibian Nightmare had ended:
https://forums.accuratereloading.com/eve/forums/a/tpc/f/6321043/m/731107049

The trophies are at the taxidermist, the shipping company is lined up, and I had a Canadian customs broker (a taxidermist), who had experience with trophy imports, lined up.

Then, this morning I got an e-mail that the Canadian broker is closing their doors for an indefinite time due to a family illness.

So, now I need to find another broker. Any suggestions, preferably in the Toronto area?

Why not do it yourself and save the money. I did it for my 2005 trophies and will be doing it again for for my 2007 ones. The procedure is quite simple. Go to the shippers office and get paperwork that came with trophies from Namibia (vet inspection cert, CITES certs, etc) . Go to customs office at airport and get it stamped. They may want to look at container. Return to cargo company, load them and drive home/taxidermist with them. On both my shipments I also had/have appendix I animals (leopard, Elephant) but all of your should be App II or III.

Appendix permit information

Tx, Canuck. The shipper has recommended the same thing. Since they will just be skull mounts, I think that's what I'll try to do.
