This is very technical, in the sense that it sounds odd, but there are a few cases from the Supreme Court of Canada, one of them called White, where in the course of a car accident a person is obliged to participate and provide a statement, and the Supreme Court of Canada held that it's a compelled statement and won't be used against the person in a criminal investigation separate from that.
C'est très technique, en ce sens que cela peut sembler bizarre, mais il y a plusieurs causes devant la Cour suprême du Canada, dont l'affaire White où, suite à un accident d'automobile, une personne a été forcée de faire une déclaration.
