Yes, it counts and is a positive. If you have travelled to many other "first world countries" and did not overstay and returned to pakistan.. then VO is more likely to believe that you will also return from Canada.
It can only weaken your tries to Pakistan if you have lived most of your adult life somewhere else, have no status there anymore, and just recently moved to Pakistan with no established roots here..
Overall, it is a big positive. Especially if you have a current visit visa to the U.S or UK.
