Quebec is not like the US in that regard, you won't find a town here that only has a Walmart/Costco. Those are limited to more developed urban centers that have plenty of alternatives.
In this region, there aren't many food/goods deserts.
Even the nowhereville my mom lives in has an H-E-B, Homeless Despot home improvement palace, pharmacy, and greasy spoon restaurants.
I have seen grocery store "deserts" in tiny towns (<2k people) populated by dollar stores while grocery stores are 10-40 miles away. That's the price of living in rural areas. There are other areas in the US where Walmart came in, destroyed local independent businesses, and left.
It's not really hyperbole, I think. The basic right is at the very least being threatened, if not explicitly violated (yet).
