REALLY SORRY FOR BEING LATE IN REPLYING
why dont u APPLY FOR phd because ur masters score is pretty good
u have to talk to supervisor at U of S i think so because in masters and phd degrees the supervisor will be the one who will decide whether to teach u or not.contact the graduate study office they can help u ,there is the link for whole process and contacts as well:

ya there are some students here who came with their family ,it depends on VO.
i think after having ur children along with u in Saskatchewan ,ur husband can apply for work permit and its processing time varies from country to country and u can check it on Cic website.it should not take too long,i hope so.
i dont know any other informative forum which can support Pakistani students.
Hope this might help
do reply to tell me how you found it...in terms of satisfaction and any other info
