Sashmir Sidney
Holder of an honours bachelor's degree in political studies from York University, a dual master's degree in public and international affairs from the same university, as well as a master's degree in international relations from Sciences Po Strasbourg, Sashmir has a rich and diverse background. Her experience at the Permanent Mission of Haiti to the United Nations in Geneva notably allowed her to develop a rigorous approach, but above all a deeply human one. She takes the time to listen, to understand each person's realities, and to seek solutions that concretely meet people's needs. These experiences have strengthened her conviction that politics must first serve people and communities. In the National Assembly, Sashmir will know how to carry the voice of the people of Rousseau, defend their priorities, and move forward the issues that truly matter to them. × I commit to voting for Sashmir Sidney as member of the National Assembly in the riding of Rousseau
