The Globe and Mail reports in its Tuesday edition that Air Canada and Chorus Aviation have extended a purchase agreement by 10 years that will see Chorus subsidiary Jazz Aviation LP continue to provide Canada's biggest airline with regional service through 2035. A Canadian Press dispatch to The Globe says that the deal quelled concerns about Chorus's future after Air Canada announced last February it would expand its Rouge fleet and fly the lower-cost airplanes on Canadian regional routes -- Jazz's traditional territory. The agreement Monday tacks on another $940-million in aircraft leasing income and fixed fees flowing to Chorus over the next 16 years, swelling the revised contract's worth to $2.5-billion in total. The amendment to an agreement from 2015 includes lowering the fixed fees and other revenue that Air Canada hands to Chorus by about $50-million annually for 2019 and 2020, a trade-off for the longer-term contract now in place. Air Canada boss Calin Rovinescu said that the contract offers his company long-term stability and cost certainty. Air Canada will make an investment of $97.3-million in Chorus, giving the airline about 10 per cent of Chorus's Class A and Class B voting shares, cumulatively.
