No fighter jet replacement contract before 2018: government guide - Politics - CBC News
This isn't the Government decision, just a recommendation. There seems to be an undercurrent to push all sorts of decisions till after the 2015 Canadian General Election. There has been talk recently of the possibility this election will be called earlier in 2015 than the mandated date. This would still allow funds to be put down late in 2015 for a 2018 delivery date for F-35. Or the decision could be thrown open. The Conservatives seem quietly confident of winning the election if the timing's right and nothing goes pear-shaped in the meantime. It is likely F-35 would be canceled if any other party wins the election.
In short, who knows?
