We have a paid Business Class flight next week on AC from YVR-YUL-EZE. Would we have access to the Signature Suite at YVR, or does it only work if the longhaul segment originates from YVR? The rules at https://www.aircanada.com/ca/en/aco/...e-suite.html#/ could be interpreted either way.

I also read the Wiki, but there is some information there I know to be incorrect, so I'm taking it with a grain of salt.
