Cargojet operates its network with its own fleet of 27 cargo aircraft. Cameron Doerksen of National Bank Financial says the contract removes the risk of Amazon operating its own fleet to supply the growing e-commerce business in Canada. Cargojet customer Canada Post has estimated that retail e-commerce sales in Canada grew 54 per cent in Canada last year to $63 billion and will reach $80 billion in 2023. Cargojet's shares gained $8.13 or five per cent at $170.37 in early afternoon trading Thursday on the Toronto Stock Exchange.
