US to Intl at YYZ
 

Hi everyone,
Flying NYC-CPH all on AC next week. When I arrive in YYZ do I have to pass through an additional security check or is it just the cursory passport check by Canadian immigration?

Thanks!

The latter. Before you descend the escalators to Canadian customs, you'll see a booth for international connections. You don't reclear security.

Thank you my friend! Much appreciated!

Although it could depend on which wing your transborder flight looks at - some gates take a separate escalator down, and you would need to walk further past it to find the booth (and skip the domestic connection gate).

Usually you can find an agent near any of the down escalators, and explain your situation.
