This feels like a pretty glaring generalization. If we look at the actual data, the story becomes a little more nuanced [1]. "Conservative" provinces have wait times that are a couple of days to a couple of weeks higher than national average (assuming we call BC, AB, SK and MB "conservative" [2]), but then again almost all of the maritimes provinces (which are considered strongly liberal-leaning) have abysmally bad wait times relative to the average (10-20 weeks worse).

Overall, the average is ~half a year anyways, which is pretty rough regardless.
