Canon has recently patented what appears to be an EF/EF-S adaptor for a full frame mirrorless camera.

This could suggest that a full-frame mirrorless camera from Canon might be on the cards in the future. The adapter appears to be designed to reduce the possibility of flare when using EF-S lenses with a full-frame sensor. The patent is translated from Japanese, but here's what's been patented:

Flange back is shorter body.

Flange back is long, a lens having the same image circle as the image pickup device body.

Flange back is long, a lens with a smaller image circle than the image pickup device body.

Mount adapter to change the diameter of the flare cut stop, depending on the image circle of mounting the lens.
