Hi,

I'm flying to Vancouver soon with the following flight path:

EWR -> PHL -> YYZ -> YVR.

I was wondering at what point will I go through Canadian Customs?

The Toronto Airport's website (https://www.torontopearson.com/Connecting.aspx#) said that I would be going through customs in Toronto, but my flight to Toronto and leaving Toronto are in the same Terminal. Do I really have to leave the terminal to go through customs and then have to wait in line to get back in?

I know the Toronto to Vancouver flight is a domestic flight so I wasn't sure at what point the customs comes into play.

Thank you
