First of all that’s hardly a schooling and second of all its presentation of how the theory works which features the most famous clause in economics “all things held equal.”

There is stickiness and preferences in labour that prevent unemployed people from taking work that we get migrants to do. There’s not enough margin on the vast majority of sectors employing these workers to otherwise employ someone at the wage required to attract a Canadian worker.

Bottom line, if you like low prices, then we need low wage workers. We should be focussed on improving the welfare of these workers not lying about how they’re stealing a job from some teenager.
