Two toric maps are equal if their three defining attributes (namely source, target, and underlying matrix) are the same.
We illustrate this test with the projection from a blow-up at a point in the projective plane to the projective plane and various identity maps.

The second example shows that we can have more than one well-defined toric map with the same source and target.
