In this commentary, we respond to Stacey Tovino's invitation to reflect further on specific legal issues she raises in relation to functional magnetic resonance imaging (fMRI) and the law (Tovino 2007). Specifically, we take up the issue of evidence law. We do this from a Canadian perspective because, unlike in the United States, this topic has not "been debated for almost 10 years" here (Tovino 2007, 44).
