Protesters descended into Snowdon Metro station Sunday to denounce Quebec's Bill 62 which requires people to show their faces when they give or receive public services.
About 70 people covered their faces before entering the station.
Many people wore scarves and surgical masks but Razia Chanda was one of half a dozen women who rode the Metro wearing a niqab — even though she typically doesn't wear one.
Her nieces wear the niqab and she felt it was important to show solidarity with them.
"I want to make sure that they're safe and they're protected," she said.
