Will be flying on CX888 HKG-YVR connecting to AC128 YVR-YYZ in a few weeks. I'm aware that there's an interline agreement between CX and AC which means CX is able to tag my bag all the way to YYZ when I check-in at HKG, however after I land and clear immigration at YVR, do I need to collect my bag at YVR baggage hall before dropping it off again prior to boarding my YVR-YYZ flight?

Too bad the direct YYZ flight CX826 no longer operates daily these days.
