The event took place in Toronto's Distillery District Saturday evening, the Toronto Star reported.
Although the carolers did not break the record, organizers said the event was a lot a of.
"I was blown away by the response of people when we put the call out through choirs, neighbourhood associations. People just love getting in the holiday spirit," said Steve Abrams, co-founder of the Mill Street Brewery and one of the organizers of the attempt.
The current record was set on Dec. 25, 2010 when 15,111 people gathered for the Hong Myung-Bo Charity Soccer Game in Seoul, South Korea and sang for 15 minutes at half-time, the Star said.
Abrams called the event a "pretty good start," saying organizers plan to make another attempt next year.
For each caroller, the organizers donated $1 to Daily Bread Food Bank.
