I just briefly looked at the map and about 90% of Canada's territory seemed clean of any dots. I know the majority of Canadians live in the South, but it still looks like there's much less users there than in the States.
The population density in Canada is one-tenth of that of the United States. So obviously, there will be less dots within Canada. But I could see a very high concentration in the Toronto metropolitan region.

Another interesting thing is that there's a lot of lonely women in India 
Can't say that. In US-Canada and the EU, somewhere between 90% and 95% of the users are male. But in India, it is down to around 80%. But still an overwhelming majority of the users in India are male. And if you look at the map, it is quite evident that the proportion of female users is higher in states such as Punjab and Kerala, where a large part of the male population work abroad.
