As Canada enters negotiations to purchase F-35 fighter jets, the federal procurement minister won't give a specific number on how much they will cost.

Appearing on 麻豆影视 Channel's Power Play on Monday, host Evan Solomon pressed Minister Filomena Tassi repeatedly on an estimated cost for the fighter jets.

鈥淒o you know the final number of the budget over the lifespan of the jet?鈥 Solomon asked Tassi. 鈥淚 can鈥檛 share the details of what the cost is because that would compromise the process,鈥 she responded.

The federal government is in final negotiations with Lockheed Martin Corporation to replace Canada鈥檚 CF-18s with 88 new fighter jets. The government previously budgeted up to $19 billion for the jets.

In 2015, the Liberal election campaign platform included a promise not to buy F-35s, saying a Liberal government would instead purchase a lower-priced fighter jet.
