You take everything to lahore VFS office. Search for their number and address on the website..
As for travelling here I would recommend direct flight PIA isn’t the most luxurious but it’s the safest as flights are direct so there’s less stress. I think lahore flights come to Toronto every Sunday..
for covid I checked the government of Canada and PIA website it looks like they just do a simple temp check and ask if you have covid symptoms before boarding the plane.. you are required to wear a mask the entire time on the plane
Make sure you have proof of a quarantine plan when you arrive here
