There are still many queries where the expected website locale isn't pulled up.
For example, if I search for "Ooma" with my region set to "Canada (CA - fr)", the US website (.com) ranks first in the results. It's followed by the Canadian website (.ca), but it's the English version instead of the French version.
See here:

I had to append the query with "Canada fr" to be provided with the right website URL to rank first.
