The agent may authorize a visitor status for a period longer than six months if it is for the purpose of accompanying ones’ spouse or parents while they study in Canada. As such, have a copy of your spouse’s study permit, TRV and passport with you.
It is becoming common for CBSA agents to not stamp passports and simply record this information electronically. It is your responsibility to be aware when your legal status in Canada expires. The default, six-month authorization is sometimes recorded in the form of a stamp and handwritten date below the stamp in ones passport. The default time period is six months, but visitor status can be conferred for longer or shorter. A person may present themselves at a Canadian Port of Entry with only a TRV or eTA. The Canada Border Service Agency (CBSA) officer can authorize the individual’s entry into Canada, as a visitor.
