Arnold grew up in the Pontiac region of Quebec, in the heart of the province’s forestry and farming sectors. Arnold’s interest in politics began at a young age when he learned about the serious threat that climate change poses to the planet and that it wasn’t being taken seriously by governments at any level.

He would first be drawn to follow Canadian federal politics while witnessing the late Jack Layton’s ability to inspire hope and courage in Canadians for building a more sustainable and compassionate society. With climate change being a priority, Arnold went on to study Chemistry and Atmospheric Science at McGill University, graduating with a bachelor’s degree in 2018 while earning a spot on the Dean’s List for Interdisciplinary Undergraduate Research. After working professionally as an environmental chemist, both in the public and private sectors, Arnold decided to pursue a doctorate in Atmospheric Chemistry at l’Université de Montréal in 2021. Over his years of research, Arnold has contributed to publications on topics of urban air quality, wildfire smoke emissions, and the properties of mineral dust from glacial sediments. Arnold has been conducting research on major environmental changes related to the recession of the Kaskawulsh Glacier in Kluane National Park, Yukon. Witnessing and studying the severe impacts of anthropogenic climate change inspires Arnold to fight for a sustainable economy and to maintain a habitable planet for this generation and those to come, all while using these opportunities to make Canada a more equitable and technologically-advanced society that is self-reliant and capable of confronting threats posed towards Canadian sovereignty and values. In his free time, Arnold enjoys playing hockey, cycling, and immersing himself in Montreal’s rich music scene.
