"made in" is completely different. A higher price is justified by supporting Americans in some way, rather than somewhere offshore.
This is more like McDonald's putting a maple leaf in their logo in Canada. It changes nothing but, apparently, Canadians like it more (I frequently watch Canadian television and non-canadian companies are frequently adding a leaf somewhere in the advertising).
That's how we can tell they aren't Canadian.
Feels like it's only U.S companies that do that, because that's what works in the States.
