I have booked round-trip tickets from Paris to Chicago, departing in a few weeks.
The return leg, operated by Air Canada, includes a connection at Toronto (YYZ). The arrival from Chicago is scheduled early in the morning, and the outbound flight is to take off around 8pm.
I would spend better time seeing the city than sitting for hours in the international terminal. As EU resident, can I get a visa to leave the airport for the day? Also, are there any left luggage facilities available?
