The City of Toronto wants to take part in the international Live Earth concert for global warming this summer, CTV News has learned.

Environmental crusader Al Gore, the former U.S. vice-president, is a key player in the free 24-hour concert that will be staged across all seven continents on July 7 and telecast to an estimated 2 billion people.

Officials at Toronto City Hall are looking for a local promoter to host the event, CTV's Tom Hayes reported.

Those behind the effort, however, don't want a repeat of the Live 8 concert in 2005, where the show was held an hour's drive north in Barrie.

"The city wants it here because it would fit into Mayor (David) Miller's green agenda," Hayes said.

More than 100 of the world's top musical acts will participate in Live Earth concerts in cities including London, Sydney and Rio de Janeiro.

Artists include Madonna, Prince, The Rolling Stones, Bon Jovi, James Blunt, Snoop Dogg, Pharrell, Faith Hill and the Red Hot Chili Peppers.

A show in Toronto would include a host of Canadian performers.

The Live Earth event is attempting to raise worldwide awareness of the dangers and solutions to global warming.

Proceeds from the live simulcast will create the foundation for a new global effort led by The Alliance for Climate Protection and Gore, its chairman.

Gore recently won an Oscar for his climate change documentary "An Inconvenient Truth."
