Many Secondary Aerodromes and Airports in Canada do not use a three element "Y" prefix. (Fully a "CY" ICAO prefix)
A few examples: Masset, BC is CZMT
Courtenay Air Park, BC is CAH3
Port Albernie, BC is CBS8
Pincher Creek, Alberta is CZPC
Taber, Alberta is CED5,
Ponoka, Alberta is CEH3
Shaunavon, Saskatchewan is CJC5
Winkler, Manitoba is CKZ7
Alliston, ON is CNY4
Some of the secondary aerodromes and airports have three-letter IATA codes as well.
Canada has over 600 airports and aerodromes. Only 13 are designated as international airports by Transport Canada: St John's, Gander, Halifax, Moncton, Fredericton, Quebec, Montreal, Toronto, Ottawa, Winnipeg, Calgary, Edmonton and Vancouver.
