"How is this not a backdoor to by-pass Canadian candidates? "
Well come on now be fair. I mean they have to wait two whole weeks before ignoring Canadians and giving the job to a TFW. Surely that is a bulletproof defence against misusing the program.
Trudeau is selling Canada out as fast as he possibly can. The question is why. Is it to get a position with the UN after Canadians kick him to the curb? Does China have something on him? Are there kickbacks to him from the wealthy? I'm betting a bit of all three.
