The commissioner of Canada elections would have the opportunity, if there is merit, to investigate if someone suggests that a false statement was made. They've been designed to be relatively easily verifiable. Something did or didn't happen.
However, the act and the commissioner are not there to be punitive. She's there to act in the public interest. If there is something that is known to be false by an individual who had the intent to disrupt.... The bar would be pretty high. It would be an offence under the act, but it would really depend on each particular circumstance. Each instance would potentially be investigated, or not, as an offence.
