David Stephan is an executive at a Canadian food supplement company. He and his wife Collet were convicted of failing to provide the necessaries of life in April 2016 after the death of their son Ezekiel who was 19 months old. After winning an appeal, the Stephans were found not guilty. This verdict was subsequently overturned and a third trial ordered. In 2021 the Crown decided to stay the proceedings. The Stephans embraced pseudoscientific ideas including alternative medicine, anti-vaccine theories and COVID-19 conspiracy theories.
