Approved ELTs

Transport Canada has added a list of approved ELTs to their website.

Keep in mind though, ELTs that are certified to Airworthyness Standard TSO-C91a will not longer be valid as Transport Canada has mandated that ELTs transmit on 406Mhz. I’m unsure when that requirement takes effect.

CAR 605.38 has more details.
