ISIS mission update, detailed costs provided by military

The Canadian military offered an update on Canada's mission against ISIS this afternoon, after releasing a detailed cost breakdown over the mission's first six months earlier in the day.

Capt. Paul Forget of the Royal Canadian Navy said Canadian CF-18 aircraft carried out only one airstrike over the last week, destroying an ISIS weapons factory on Feb. 13.

Previous briefings have detailed Canadian airstrikes and times when special forces have come under fire, along with the military's views on how ISIS has been affected by the international coalition's work.

The briefing comes on the day Defence Minister Jason Kenney has released a detailed breakdown of cost estimates for the 2014-15 fiscal year.

Of the $139.6 million requested for military operations, Kenney said approximately $122.6 million is for the first six months of Operation Impact in Iraq.

That figure includes:

- Just over $73.5 million for aircraft maintenance, fuel and operation, plus ammunition.

- Around $34.1 million for meals and accommodation.

- More than $8.8 million for "allowances" for around 600 of the people who are deployed, including hardship and risk allowances plus the government-mandated benefit program.

- $2.2 million for "other personnel-related costs" including meals and transportation for people to and from where they're deployed.

- Just under $550,000 for vehicles.

- Around $3.3 million for "other costs" including camp setup, local purchases and other "miscellaneous amenities."

The other $17 million is for Operation Reassurance, which is Canada's contribution to the NATO Ukraine mission.

"This is not a guesstimate … those are the funds that we require for supplementary pay, for fuel, for operating cost and all incremental costs associated with Operation Impact," Kenney said Thursday.

"If we were to wrap up the mission and bring people home there would be additional costs in terms of the mission and if we were to extend the mission, obviously additional costs."

Earlier this week, the Parliamentary Budget Office said the cost of Operation Impact over that same six-month period could be anywhere from $128.8 million to $166.4 million.
