Josh,
Canada is a LOT bigger than Britain. I took the train from Winnipeg (close to the geographic center of the continent) to Vancouver BC - it took 3 days. We got to go through a tunnel in the mountains too.
The three biggest countries by surface area:
# Russia: 17,075,200 km2 (6,591,027 mi2)
# Canada: 9,984,670 km2 (3,854,082 mi2) population 2006 census was 31,612,895
# United States: 9,631,418 km2 (3,717,727 mi2)
# UK: 245,000 km2. (50,351 mi2) population 2001 census was 49,138,831
So you can see that the population of Canada is a LOT more spread out. Although not evenly. Most people live within 100 miles of the US/Canada boarder. So think of it as a really wide narrow band of population. From Victoria to Newfoundland is 8,000 land kilometers (5,000 mi), although Newfoundland is a pretty long way off the coast - its actually closer to London than to Ottawa and has its own special 1/2 hour off time zone. The distance from London to the Orkney Islands is 848 km (air miles). And they are fairly close to opposite ends of the UK.
