| contents | The search for neutrinoless double beta decay has internationally been recognized as the most promising approach to determine the Majorana nature of neutrinos. This hypothesized decay would, if observed, violate lepton number in weak interactions by two units, hence, prove the existence of physics beyond the Standard Model. Current experiments with sensitivity to neutrinoless double beta decay half lives of $10^{26}$ years did not observe such a decay and worldwide efforts are ongoing to deploy experiments with half-life sensitivities beyond $10^{28}$ years. Canadian groups have been involved in this search for more than four decades. This article summarizes the historical experimental efforts and describes current Canadian contributions to neutrinoless double beta decay searches and their theoretical interpretation. |
