Most people live in urban areas though. Nova Scotia has only a million inhabitants and half of them live in Halifax where I assume the Apple Store is. If something needs fitting and prescription lenses it seems reasonable that a physical location needs to be visited and this is the kind of trade off one makes when moving to a rural area. I'd bet that this will still be convenient for the vast majority of the population.
That one store in Nova Scotia is pretty much the Atlantic Canada store being the closest for most people in Newfoundland, PEI and a huge chunk of New Brunswick (on the Western side the Québec City store is closer maybe, still hours away). There's plenty of non-rural areas there without an Apple Store.
There is still 4 U.S states that lack an Apple store entirely. It's not like Wal-mart or even Best Buy.
