The city of Calgary has cancelled this year's edition of its free, public Bright Night event, which is normally held every New Year's Eve.

The all-ages celebration usually takes place downtown at Olympic Plaza, but with uncertainty over when the plaza's ice rink upgrades would be completed, the city had to nix the festivities to ring in 2010.

"There was music in the past and some programming on the stage, but that has been cancelled. With the ice plant upgrade underway, we weren't certain about when the ice would be in place," said Trish Neufeld, an events manager with the municipality. 

"Calgarians are still welcome. The ice now is in place, so Calgarians are welcome to go down and skate. But the balance of sort of a formal program isn't going to be happening this year."

Bright Night typically ran from 6 p.m. to 12:30 a.m. by the colonnade at Olympic Plaza, across from Old City Hall. Past editions of the celebration have included musical acts, arts and crafts for children, stage performers, fireworks, food vendors and ice skating for the public.

Neufeld said the event should be back next year.
