Hudson started the Toronto chapter of Black Lives Matter after being encouraged by her brother to do something following the police killings of Mike Brown and Jermaine Carby. Thousands attended a solidarity rally that she organized with Janaya Khan. After the rally, they contacted Patrisse Cullors to establish the group as the first official chapter of Black Lives Matter outside of the United States. The group has challenged different forms of anti-Black racism in Canada, and has made issues like carding and defunding the police national conversations.
