The Use of Phallometric Evidence in Canadian Criminal Law

Results of the search of the general Canadian legal database (LexisNexis Quicklaw, All Canadian Court Cases¹²). The specific search string was “phallometric or plethysmograph!” The database used includes federal and provincial courts across Canada, but excludes boards and tribunals. The search yielded 397 citations, from which we removed duplicates and incidental references to phallometry unrelated to the use of phallometric evidence in that case (e.g., cases in which phallometric evidence was not at issue, and the reference to phallometry was in the context of the general rules of evidence law discussed in the decision of the Supreme Court of Canada in R. v. J.-L.J.,⁵ which addressed phallometry).
