This is analytical work that we need to engage in, but in the U.S., there's been evidence of highly concentrated labour markets. We might think about rural or remote communities, but it's even in relatively large urban centres.
What we need to think about, with Canada having relatively high levels of concentration and more oligopolies than our friends in the U.S., is that it would make sense that the effect is the same or is magnified, such that workers are limited and can be, prior to changes, frozen out through no-poaching agreements and wage-fixing agreements.
