Samuel is also involved internationally for the protection of the human rights of individuals in vulnerable situations. In 2018-2019, he volunteered with Lawyers Without Borders Canada for a year as a legal advisor in Haiti as part of the Access to Justice and Fight Against Impunity project. To this day, he continues to take part in implementing this project.
