> I'm curious as to how many problems rats really cause in a modern city.

For context, there is a lot of farmland in alberta. I think the reason for this is more to protect agriculture than city drewlers.

But also rats are icky.

a basic problem is their easy population explosion. As soon as you allow a sizable population of them to thrive, it becomes very hard to keep them in check in the places where you really don't want them. In my smallish european city, we have a few food courts. The outer doors are normally open/ajar in day time. I really really don't like seeing rats scurrying about under the benches and obstacles when I visit there to eat.

yes it's the agricultural impact, both real and perceived (most of Alberta's crops are export-bound).
