Two topless protesters crashed an anti-abortion rally on Parliament Hill Thursday afternoon.

Being topless is legal in Ontario, however the RCMP says the pair were arrested for “causing a disturbance.”

The demonstrators interrupted the 17th annual National March for Life rally held by the Campaign Life Coalition, which this year focused on banning abortion drug RU-486, still under review by Health Canada.

The women, who had phrases like “my body, my rules” painted on their bodies and on signs, are part of an international activist group called FEMEN. The group describes themselves as a collection of “brave, topless, female activists painted with slogans and crowned with flowers.”

The RCMP confirmed two females were arrested, and that the pair were issued a trespass notice under the trespass and property act and released from custody.
