a) No. A TRV only allows you to visit Canada as a tourist.That answer was really helpful. I just ha the same question in my head.
may you please elaborate little bit more on my express entry side?
a) If i go on TRV, will i be able to work part-time? so that i can count that as a Canadian work experience and continue my Express entry PR application?
b) I need to stay for one year to become the common law partner, may i work there during this time as well?
c) what will happen if i receive ITA during the 12 months when i am living with my boyfriend?
b) See above. A TRV only allows you to come to Canada as a tourist. If you want to work here, you need a job offer from an employer in Canada and that employer will need to obtain an approved LMIA so that you can apply for a closed work permit.
c) You would go through the same process in applying as you would outside of Canada.
