I was flying from Kingston, Ontario to Boston in January on Air Canada and I was to connect in Toronto. Due to a freezing rain storm, Air Canada cancelled their flights to Toronto, but Canadian Airlines was still running in Beachcraft 1900D aircraft (I have never felt so close to a near disaster. Never fly those aircraft in ice!) Anyways, Canadian accepted my flight coupon, but of course Air Canada did not want to give me the miles. A letter to the Aeroplan Elite Centre corrected that in a hurry! I was shocked when they told me on the phone that they usually do not give miles for a cancelled flight. I have yet to figure out if they added to my qualifying miles,segments total! I hope so, otherwise I will need to write another letter.
