If you proceed to Canada alone, it is possible that your dependants will not be able to join you there. If you wish your spouse and / or child to accompany you to Canada or to join you at a later date, you must provide proof that you will be able to support them. Please see the response to Question 9 above.
Since funding provided by Canadian institutions or governmental organizations is normally sufficient for one person only, you will likely be required to provide proof of additional funding and/ or savings. Your dependants will also be required to demonstrate to a visa officer that they have sufficient ties to India to ensure their departure from Canada.
