Oh wait till you get out of this small tip of Southern Ontario (from Toronto to Windsor), 401, 403, and 407 are the crown jewels of Canadian highways. The Trans Canada highway, for example, becomes as below as soon as you enter Ontario. Undivided two lanes. So good luck driving beyond Thunder Bay along lake Superior at night when the lake blows thick fog over the highway and you can't see anything, which btw happens every single night.
You won't call this a Motorway/Expressway in Pakistan.
Westwards through Manitoba, Saskatchewan and Alberta it's two lanes divided and then in BC its a mixture of both.
It really is.
Not kilometers wise but from the little experience I have on US highways, quality and comfort wise I'd guess Pakistani Motorways and Expressways are neck and neck.
