Hey everyone. This March I have an international flight from Dallas-Fort Worth to London Heathrow.

I'm flying Air Canada Jazz from DFW to Toronto Pearson, and I'm flying Air Canada from YYZ to LHR. However, my layover in Toronto is only two hours or so.

Will I need to go through Customs and Immigration at YYZ after getting off my first flight?

Also, will I need to go through Passport Control and additional security screening before boarding my transatlantic connecting flight?

Last year, when I flew from DFW to Rome, I had a layover at LHR- where I went through Passport Control and a long security checkpoint. I don't know if my layover at YYZ will be the same.

This will be my first time transferring from one international flight to another. And with a two-hour layover, I better not miss my flight to London.

So how does the transfer process work for connections between international flights?

Should I go ahead with my scheduled itinerary?
