When you apply for a temporary resident visa for Canada, you must satisfy the visa officer who reviews your application that you

* will leave Canada after your temporary stay

* have enough money to support yourself and family members while you are in Canada, and enough to return home
* do not intend to work or study in Canada unless authorized
* will be law abiding
* have no record of criminal activity (a Police Certificate may be required)
* are not a risk to the security of Canada
* are in good health (a medical exam may be required)

Your passport should be valid for at least three months from your intended date of arrival in Canada, since the validity of a temporary resident visa cannot be longer than the validity of a passport. If your passport is getting close to expiring, then have it renewed before you apply for a temporary resident visa. You must also produce any additional documents requested to establish that you are admissable to Canada.
