I'm looking to book a flight for my family YOW-YYZ-MKE. The inbound flight arrives at 7:05am and we depart for MKE at 8:35am. We all have NEXUS and checked baggage. How tight of a connection will it be? My concern is that if we miss the flight for some reason, the next AC flight to MKE is 10 hours later. Would we be re-booked on another carrier or would we have to wait?

Thanks
