Air Canada regional subsidiary Jazz Aviation began operating its first 74-seat Bombardier Q400 turboprop on June 7 on a route linking Toronto Pearson International Airport with Quebec City. On May 26 the airline took delivery of the first of 15 Q400s, all of which will replace 50-seat Bombardier CRJs as the delivery schedule stretches into July 2012. Jazz also holds options on another 15 airplanes. Fellow Air Canada affiliate Sky Regional Airlines launched the first direct competition against Q400 rival Porter Airlines out of Billy Bishop Toronto City Airport on May 1, when it began service between the downtown Toronto airfield and Montreal.
