Companies in the news:Transat A.T. (TSX:TRZ). Down 42 cents or 2.5 per cent to $16.19. The fate of Air Canada’s $720-million takeover bid for Transat A.T. Inc. rests with regulators after shareholders overwhelmingly approved the acquisition offer Friday. In a special meeting, shareholders of the Quebec-based tour operator voted 94.77 per cent in favour of accepting the $18-per-share transaction from the country’s largest airline. The deal will narrow the field of airline competition, securing for Air Canada about 60 per cent of the Canadian transatlantic market and helping the company maintain a firm hold on Montreal air travel.TC Energy Corp. (TSX:TRP). Down 42 cents to $64.37. One of the last major hurdles for the Keystone XL crude oil pipeline was removed on Friday by the Nebraska Supreme Court which rejected an attempt to force the developer to reapply for state approval. The court upheld the decision of regulators who voted in November 2017 to greenlight a route through the state. The court’s decision was a victory for the US$8-billion project, which has been mired in lawsuits and regulatory hearings since it was proposed in 2008. The Nebraska Public Service Commission voted 3-2 in favour of an “alternative route” for Keystone XL instead of TC Energy’s preferred pathway for the pipeline.Cargojet Inc. (TSX:CJT). Up $11.66 or 12.86 per cent to $102.33. Shares in Cargojet Inc. shot to a record high Friday after the company announced a new deal with Amazon.com that could see the online retailer acquire a stake in the company that provides overnight air cargo services. Amazon already uses Cargojet’s charter aircraft services to move packages from Amazon warehouses to distribution centres for final delivery, but the deal announced Friday is designed to encourage it to use the network even more. Under the agreement, Mississauga, Ont.-based Cargojet will issue warrants to Amazon for variable voting shares that will vest based on milestones of business that Amazon gives Cargojet.
