When Must an Anti-SLAPP Motion Be Heard?
Ontario’s Anti-SLAPP legislation (ss 137.1 to 137.5 of the Courts of Justice Act) provides a judicial screening device. It is designed to swiftly eliminate claims that unduly limit freedom of expression on matters of public interest. Since coming into force, courts have considered, at length, the substantive issues. To date, little guidance has been provided on the procedural issues.
