In case anyone is curious, southern Ontario is quite south of the 49th parallel and includes Canada's biggest city.

The population of southern Ontario is ~13.5 million people (roughly a third of Canada).

North Korea has a similar area (slightly larger), but approximately twice the population. South Korea also has a similar area (slightly smaller), but approximately twice the population of North Korea = four times the population of southern Ontario.

In particular, ~13.5 million more people live in South Korea (which has an area smaller than southern Ontario) than in the entirety of Canada.
