The logic for me would be that if you take the de minimis, let's say it is raised, then in a sense there's an issue of sacrificing your sovereignty, your national independence to make certain decisions. I'll go to minimum wage. To build a robotics facility in southern Ontario or in the upper Michigan peninsula, obviously you'd look at unemployment rates, accessibility of labour, and minimum wage.
If you raise the de minimis, effectively you're probably removing your freedom to make other choices of public policy, which as a nation we'd probably regret and we'd be dragged down to a lower level. The regional impact is more in regard to where people will localize their businesses.
