Historically, Canadian airports had 2 letter call signs, then added a Y prefix if the airport had a weather station, and a W if it didn't, so pilots would know how much weather information they could expect when planning a landing. Basically any major airport had a weather station, the Ws were just lonely little airfields.
When the IATA mandated 3 letter calls signs, that format was already in place.
