OTTAWA - Prime Minister Justin Trudeau has appointed new senators for Nova Scotia and Manitoba.

Mary Coyle, a champion of women's leadership, gender equality and the rights of Indigenous Peoples, is the new senator for Nova Scotia.

Mary Jane McCallum, a First Nations woman who provided vital dental and health services to northern, First Nations, and Indigenous communities during her career, will represent Manitoba.

Coyle worked in international development in Indonesia, pioneered the development of a micro-finance bank in Bolivia and helped establish the First Peoples Fund to provide micro loans to First Nations and Metis communities in Canada.

McCallum practised as a dentist, was a community leader in several areas across her province and led the University of Manitoba's Aboriginal dental health programs.

These Senate appointments are the 29th and 30th Trudeau has made since taking office.
