A backlog of flights out of Toronto is delaying the arrival of some Canadian figure skaters set to compete at an Olympic qualifying event in Ottawa.

The 2014 National Figure Skating Championships open Thursday at the Canadian Tire Centre, but the actual events do not begin until Friday.

While senior competitors were supposed to start arriving Wednesday for the championships, many flights have been delayed, according to Skate Canada's director of events, Jackie Stell Buckingham.

Stell Buckingham said it's too early to determine whether any events need to be rescheduled.

"We are still in a bit of wait-and-see [situation] but we are starting to make contingency plans if we have athletes that can't make it for their regular scheduled times," said Stell Buckingham.

First scheduled competition Friday at 12:10 p.m.

She said many of those affected are officials, suppliers and technical crews, some of whom have already made alternate arrangements via train to arrive in Ottawa on time.

The first scheduled competition on Friday is the Senior Women Short Program at 12:10 p.m. ET, but many athletes were hoping to use Thursday for their practice skates.

"We are starting today to look at the competition schedule and look at the worst-case scenario in case we have athletes that can't make it, or if they miss their practices tomorrow, what can we do to make sure they can still prepare properly and compete just like they would if none of this had happened," said Stell Buckingham.
