1. Small child get cranky when confined, transit is better. Layover should be about 3-4 hrs. Kids when get off plane might use rest room at wrong time. Also there might be airport rush. Always good to have extra time on hand if traveling by economy
2. BA , best baggage allowance, best early check-in policy, European, dreamliners, no transit visa requirements if airport remains same. Read my post on air ticket a few pages back on this thread only.
3. Clothes and typical utensils countable like cooker, kadahi thats it, as they are costly in Canada. Check amazon.ca , rest all you will get there. Winter clothes buy from Canada, buy branded interview clothes , regular casual wear and inner wear and thermals from India.
4. Check air bnb and kajiji . Booking before landing is always better. Believe me. Response is slow so look extensively. Don't look at down town instead look for away and near to train and subway.
5. Best Is to open an account from India and transfer your fund. Safe , cheap to transact. Find a post on same a few pages back in this thread only by me. RBC is the most responsive and no.1 bank of Canada
