Canada has a long history of shedding core national interests to corporate America. The oil sands were developed by PetroCan, a crown corporation. Now, all the oil sands are owned by Americans. The entire Avro Arrow program was scrapped and burned (and the ground was salted) for an unknown reason to me, other than Americans. Connaught Labs, a world renowned developer of life saving vaccines was sold to Americans. The Canadian Wheat Board was dismantled, I think Saudis were involved, most likely supported by Americans. The list is endless. Canadians have to learn to value the things they develop.
