Determining if you have access to Air Canada’s Maple Leaf Lounges depends on your ticket class, Aeroplan elite status, or specific credit card benefits. Generally, if you are flying in Business Class or Signature Class on an Air Canada-operated flight, your boarding pass is your "golden ticket" for entry. Additionally, Aeroplan 50K, 75K, and Super Elite members have complimentary access regardless of their class of service. If you hold a "premium" Aeroplan credit card (like the American Express Aeroplan Reserve or the TD/CIBC Visa Infinite Privilege), you also receive unlimited access for yourself and a guest. For those in Economy without status, you can check your booking on the Air Canada app or website; if you purchased a "Latitude" or "Comfort" fare, you may have the option to add lounge access for a fee. Finally, Star Alliance Gold members flying on any Star Alliance flight departing from the same terminal are also entitled to entry. Always check the digital version of your boarding pass, as it usually features a "Lounge Access" indicator or a QR code for seamless entry at the lounge front desk.
