Talking about the overall size of Canada is dodging the issue. The scale of the country does provide a justification for not being able to access any arbitrary spot across Canada (or the US) using public transport, but the previous commenter is talking about accessing a town a mere 200 km away from British Columbia's largest city and urban agglomeration — 3rd largest in Canada as a whole.
How many Switzerlands can you fit within a 200 km drive from Vancouver [0]? My eyeball guess is that the area is half the area of Switzerland, maybe less than a third if we exclude US territory covered in the map. And what's the population density of that area? Again, ignoring the US, just counting Vancouver's [1] and Victoria's [2] metropolitan areas alone adds up to 3,000,000 inhabitants (more than a third of the population of the whole of Switzerland), so this area's population density is very likely to be similar or even greater than that of Switzerland as a whole.
