said by FiReSTaRT:A foreign government doesn't give a flyin' fuck about what a Canadian individual is doing with his home Internet account. Those backdoors would kill the company's sales, so chances are that they aren't in there in the first place.
But they MAY be in the new Huawei/Bell Mobility Canadian cell towers along the US border, listening to any US phone transmissions that the Chinese may find interesting.
If you think this is far-fetched, consider the US EP3 planes that continuously fly dangerously close to the Chinese mainland, in Taiwan straits, and the south China sea, listening, listening.
China has to get back at the US somehow.
