Saifur, I am fully agreed with t119 and mgmbbd. uRegina is a very good choice other then the rough weather of Saskatchewan. Which course type u choose? I got acceptance with funding from uRegina too in M.Sc. Computer Science (Thesis). So, I have a bit knowledge about it.
There r three types of M.Sc. in Computer Science (Thesis Based, Project Based & Co-op). Only Thesis Based is funded and other two r self funded course. All those types are not less than 2 years course. so u have to calculate the total cost of 2 years. Then 24,600 * 2 = CAD 49,200 = BDT 39 lac. Beside it will be best idea to show not less than this amount of liquid money during visa to be safe, if u go through as a self funded student.
Take ur time and plan step by step. Its took time... Mine took 9 months to learn and process this whole thing.
