Given a pair $M,M'$ of finite-dimensional modules over a domestic canonical algebra ${\mit\Lambda }$, we give a fully verifiable criterion, in terms of a finite set of simple linear algebra invariants, deciding if $M$ and $M'$ lie in the same orbit in the module variety, or equivalently, if $M$ and $M'$ are isomorphic.
