It doesn't interact with provincial legislation. This is a federal animal health act. What you and maybe Mr. Perron are talking about is a Criminal Code issue. Yes, provincial police forces can lay a trespassing charge if there is a protester unlawfully on private property, but the CFIA could also press charges through the Health of Animals Act.
As I said, three provinces, maybe four, are working on similar legislation through the Criminal Code, specifically on trespassing when it comes to protecting biosecurity on farms, but only Alberta and Ontario now have that legislation. Saskatchewan is going through the process, as is Manitoba, but that still leaves a majority of provinces and territories without anything in place. I think it is important that we show some leadership at the federal level on this.
