All applicants wishing to visit Canada must satisfy the immigration officer that they will leave Canada by the end of the period authorized for their stay, that they will not contravene the conditions of admission under this class (for example, that they will not study or work without prior authorization), and that they do not belong in a category of persons inadmissible to Canada under the Immigration and Refugee Protection Act.
In reaching a decision, an officer considers several factors, which include:
Documents required for Business class visa
Single or Multiple entry Business visa
Single entry business visa: A single entry visa allows you to enter Canada once. If you leave Canada before the visa expiration date mentioned on single entry visa, you must get a new visa to re-enter Canada.
Multiple entry business visa A multiple-entry visa allows you to enter Canada several times during the period while your visa is valid. A multiple-entry visa is valid for a maximum of five years or one month prior to the expiry date on the passport/re-entry visa, whichever is earlier.
A foreign national can apply for an extension of his or her visitor visa within Canada. As long as the application for extension of status is made before the end of the authorized period of stay and the foreign national has complied with all of the previous conditions imposed on his or her entry into Canada, the extension will be allowed.
