A bike helmet must meet specific standards. In Ontario, acceptable helmets are those that have been tested and meet one of these standards: CSA, Snell, ANSI Z90.4, or other standards that are acceptable in Ontario. These helmets should have stickers indicating their compliance with the respective standard.

Moreover, helmets should fit securely and not move around on your head or cover your ears. The chin strap should be securely fastened under your chin.
