Skate Canada is looking into Canadian options to host the displaced world figure skating championships.

Japanese organizers have told the International Skating Union they cannot stage the event and the sport's governing body plans to select a new site for the competition by the end of this week.

The championships were scheduled to begin this week in Tokyo but were postponed due to the earthquake and tsunami that have left Japan in crisis.

The ISU had offered Japan the possibility of hosting the world championships in October, but the Japan Skating Federation wrote back over the weekend saying it was handing the competition back to the ISU.

ISU president Ottavio Cinquanta told The Associated Press on Monday he has asked members capable of hosting the worlds in late April or early May to send offers by Tuesday, and the ISU council will then vote Wednesday or Thursday.

In a letter to members, the ISU said such countries need an arena with at least 8,000 seats as well as a practice rink, about 700 hotel rooms and ability to televise the event.

"I think it's great they've decided to go ahead with worlds," said Meryl Davis, the Olympic and world silver medalist in ice dance with Charlie White. "The main concern was making sure we did what was right for Japan and remaining respectful toward Japan and what it's gone through. Now that Japan has vocalized it's OK with worlds going on, I think it's definitely the appropriate decision."

Cinquanta hopes to have at least three or four candidates, and possibly seven or eight.

"We'll see what comes in and then we hope to have an announcement by Friday," he said. "We're trying to move as quickly as possible. We gave Japan as much time as we could, but unfortunately the situation there is very serious and we've had to move on. But our thoughts are still with Japan."

U.S. Figure Skating told the ISU last week it could host the championships in either the arena in Lake Placid, N.Y., or the World Arena in Colorado Springs, Colo. Neither arena meets the 8,000-seat threshold, but U.S. Figure Skating believes both would be "strong" bids.

Both cities have experience hosting international skating events; Lake Placid hosted Skate America in 2009, and Colorado Springs recently was chosen as the site for next year's Four Continents Championships. Most larger arenas in the United States are unavailable due to NHL and NBA games.

Skate Canada has also told the ISU it would help out in whatever way it can, and CEO William Thompson said Monday the federation was exploring whether to make a bid for worlds.

"[We] will submit a hosting bid if we can find an appropriate location with arenas, hotels and transportation infrastructure," Thompson said.

The massive March 11 earthquake and tsunami that devastated northeast Japan likely left more than 18,400 people dead.

The Japanese federation also agreed to postpone the ISU World Team Trophy, scheduled for April 14-17 in Yokohama, until 2012 at a date and site in Japan to be determined.

"We've been trying to keep perspective and realize so many people are dealing with things that are true problems and things that are life-changing," Davis said. "At the same time, it is a huge challenge because our sport, like so many, is based on peaking at the right time. … Now that we know for sure the ISU is going to go ahead with worlds, it is reassuring."
