Abstract: This paper presents new examples of projective surfaces of general type over C$\mathbb {C}$ with canonical map of degree 3 onto a surface of general type. Very few examples are known of such surfaces and some of the examples in this paper present the new feature of having the canonical map not a morphism (i.e. the canonical linear system with base points).
