Air Canada MD11

Does anyone have any info on why a daily flight keeps showing up Toronto to Frankfurt operated by Air Canada using an MD11?

To my knowledge Air Canada does not operate MD11s


Perhaps a regular charter (almost daily YYZ-FRA, every other week for YHZ-VIT) under an ACMI lease?

World Airways leased to Air Canada just for the cargo schedules.

The Air Canada cargo flights also operate to Asia. Here’s the air cargo schedule
