It is really awful. Particularly, but certainly not exclusively, out of YYZ.

I am flying the family YYZ-YVR over the summer. We almost booked out of BUF until a seat sale came up.

Flew BUF-LIR last year - saved well over one thousand dollars.

Sure I want to support Canadian airlines and pay taxes to the Canadian government which pays for goods and services I use . . . but with this type of price discrepancy I simply cannot justify it.

Ah well USA needs the revenue too.
