In March 2014, Winston Blackmore and James Oler were charged with polygamy; their prosecutions were the first such cases in Canada in over sixty-five years. In 2007, an independent prosecutor in British Columbia recommended that Canadian courts be asked to rule on the constitutionality of laws against polygamy. The Supreme Court of British Columbia upheld Canada's polygamy laws in a 2011 reference case. On March 9, 2018, the Supreme Court of British Columbia reaffirmed the constitutionality of Canada's anti-polygamy laws, upholding the July 2017 polygamy convictions of Winston Blackmore and James Oler.
