Fine. Thrown in the saraha desert and a few other inhospitable areas and it'll make up that third.
> And a significant amount of it is also Siberia and Mongolia.
Are we looking at the same map? Hardly any part of siberia is included ( maybe the a tiny portion of the russian far east ). Feel free to take out the mongolian landmass if you want.

Did and my idea still holds.
Your math may be accurate, but your assessment of habitable land-mass seems to be off.
I know and work with a number of people in Canada, and I've visited many, many times. I'd hardly consider the entire area of Canada "uninhabitable". (Per wikipedia [1], Canada has a total (non-water) area of 3,511,023 sq. mi.) 37 million people live Canada [1].
Also, just a quick visual check indicates that about 1/2 of the area within that circle is ocean. And, the population density of the Himalayas (which is in the circle) is arguably small as well.
But, still I wouldn't consider the entire country to be "uninhabitable"

Eg. India has 43% of it's land classified under "others" [0]. A large chunk of that 43% is not likely to be habitable.
