You need atleast CAD 1300 to 1400 a month to meet up all cost (house rent with hydro + food + transport +internet & mobile) for 3 to 4 members family. You will get CAD 400 approx. for each of the babies. If you have two babies, house rent can be financed from this allowence. You need to earn the balance CAD 500-600 just to survive. Our target should be not to exhaust the money we will be carrying from Bangladesh rather keep it intact for the uncertain future.
Just after landing one should not rush for taking admission in any college or university. Try to grab a job from the very first week. Hourly pay would be CAD 9.5 to 10.5 for survival job and try working for 40 hours a week .
After 3 months research and settleing down, one may decide which field to study !
My friend, xxxx, after finishing Supply Chain Mgt. Diploma is now working as a material coordinator in an engineering company and earning CAD 2000/month after tax where as, my friend's husband is driving TAXI in New York City during nigh time and earning USD 4000- 5000 a month. Another friend of mine did not like the taxi cab occupation, and opted to work in a hotel as a front desk officer and he is happy with USD 1960 a month after tax without taking any US degree (He has MBA Degree from DU, with Accounting major).
So, situation and circumstances will lead you the way ! Land in Canada , be prepared for the worst and be optimistic for the best.....success will be on your way ~
