It is a troubling time to be an animal rights activist in Canada. Recently, Alberta adopted legislation to create harsh penalties for trespassing onto private property, for obtaining permission to enter private property based on false pretences, and for interfering with vehicles on public highways. These laws relate to agricultural lands, to private property generally, and, where roads are concerned, to public property. Ontario has adopted similar legislation aimed specifically at agricultural property. The legislation in both provinces purports to protect the security of farmers, their families, and rural property owners generally, as well as the safety of the food system, by preventing contamination of farmed animals by trespassers and those who would interfere with farmed animals in transport.
