This is a privately owned and operated business that provides "registration services". This is where one goes to register a vehicle in the provincial government's registry of motor vehicles, renew drivers' licences (and/or to undergo driver licence testing), land titles, corporations, to add one's name to the organ donor registry, etc. These are all government registries, but all of the public-facing aspects of the registries are handled by these private agents.

I brought this up tangentially in a recent discussion about the "government=register_office" tag: https://community.openstreetmap.org/t/is-the-government-register-office-tag-being-used-correctly/101291/2 I have personally added one of these registry agents using the "office=government, government=register_office" tags, e.g. https://www.openstreetmap.org/node/5286594240, but (per the linked discussion above) I'm not really sure there is an existing tag that makes sense here. It's a private enterprise, a "shop" per se, but it's one that just deals with government registries and registration 'services'.
