In any case, that's the "official" response to clear up any confusion as interestingly, this is not listed at the current Canadian Amex The Platinum web site and the landside arrival lounge is definitely not part of the Priority Pass programme, only the two airside lounges. Just a friendly reminder - benefits of the American Express The Platinum card vary between countries where the card is issued/domiciled. The foregoing applies only to The Platinum card issued by American Express in Canada.
