The stage was stormed by a young woman who wore a pink bandana, pink pants, and pasties over her breasts.

The lady had blonde hair and wore blue rectangular eyeglasses as she took a stand against the Ontario Greenbelt development.

The unknown woman had written ‘Save the Greenbelt’ and ‘Land Back’ on her inner arms.

Lavigne did her best to ignore the person, walking around her as she continued to read from a monitor.

By the time she took the stage Avril had changed into a shiny black trench coat.

Losing her patience after a few moments, the Girlfriend singer told the woman to ‘get the f*** off’ the stage.

She laughed and repeated herself as she said, ‘Get the f*** off, b****!’ as a suited man escorted the protester off the platform.

News outlet CP24 reported, ‘In November, the Ontario government issued new regulations to remove 7,400 acres of protected Greenbelt land and open it up for housing, with construction to begin by no later than 2025.’
