We construct a surface of general type with canonical map of degree 12 which factors as a triple cover and a bidouble cover of \mathbb P2. We also show the existence of a smooth surface with q=0, χ=13 and K2=9χ such that its canonical map is either of degree 3 onto a surface of general type or of degree 9 onto a rational surface.
