It’s official: according to organizers with the recent Up Here urban music and art festival, Sudbury is now home to Canada’s largest mural. The annual festival celebrates music and art. Each year, murals are painted throughout the city.  Los Angeles-based graffiti artist RISK spent 13 days painting the old general hospital on Paris Street. Festival co-founder Christian Pelletier says the final project is 74,000 square feet. He says a mural in Thompson, Manitoba previously held the title with a 20,000 square foot mural of a wolf. “The intention of this project was to cover as much wall as possible on that hospital to make it a little surreal, a little wonderful,” he said.
