Mayor Martin J. Walsh's plan to host a televised public viewing of the NHL Winter Classic in Copley Square on New Year's Day has been canceled due to a dispute over broadcast rights.

On Monday, city officials said they had partnered with the NHL to live stream the Bruins-Canadiens game, which will be played at Gillette Stadium on Jan. 1, on a big-screen TV in Copley Square. The free event was to be part of the city's First Night/First Day festivities.

But on Tuesday, TD Garden officials notified City Hall that NBC will not grant Boston the broadcast license needed to make the event possible, according to Walsh spokeswoman Laura Oggeri. Before receiving that news, city officials had been "under the impression that all the logistics had been finalized," she said.
