This was based on a post on the CALL listserv; many thanks to Michèle LeBlanc of the Université de Moncton for the information.
The Centre de traduction et de terminologie juridiques (CTTJ) at the Université de Moncton has been working on a project to translate important unilingual Canadian court decisions into Canada’s other official language. The project currently focuses primarily on the areas of criminal law and family law.
The translated cases are available here: https://www6.umoncton.ca/cttj/jurisprudence-pancanadienne/ and can be searched by style of cause, file number or jurisdiction. The translations can also be found on CanLII.
