My Spouse visa is under process. I am in Canada on TRV multiple entry visa. First I entered on 20th September 2019. I left Canada on 2nd Nov 2019 to give biometrics. Again I came to Canada on 4th November 2019. CBSA officer stamped Nov 4th on my passport which means I can stay six months from Nov 4th right? Or whether six months counts from my first visit(20th september)?
