Canada's airports used two-letter codes before the IATA system

While most Canadian airport codes begin with "Y," there are a few exceptions, such as Shamattawa Airport (ZTM) in Manitoba and Edmonton/Villeneuve Airport (ZVL) in Alberta. Additionally, a few airports outside of Canada also start with the letter "Y," including Yakima, Washington (YKM) and Yuma, Arizona (YUM) in the US.
