This depends on many factors like where you planning to live, number of dependents (either coming with you or back home), groceries, eating out, entertainment etc.
I'm thinking of bringing about $8500 with me (cash or forex card not decided). I don't have a job in place yet so this should help with 2/3 months of expenses in Ontario (not sure which city to live in yet). I'm in tech so probably Toronto, Kitchener, Ottawa.
What about you? What are your plans?
Maybe others can also pitch in so we all can make an informed decision.
