As my whole family (me, my wife and 2 sons) plan to visit Canada this summer on a Temporary Resident Visa (We got TRV) and intend to apply for the Provincial Nominee Program (PNP) in Alberta. The processing time is approximately 5 months. During this period, we have two children, with one entering 3rd grade and the other starting 9th grade in the upcoming semester. As temporary residents, can we enroll them in public schools while awaiting the PNP results, and are both public and private schools options for them?
