We benchmark regularly across a wide spectrum of roles, industries, sectors, and levels to ensure our ranges are both competitive and current. But we don’t stop there. We also consider the unique strengths, experiences, and impact each individual brings to the table. Our salary ranges are reviewed annually, and where you land within the range depends on a mix of factors—your background, your skills, and how your contributions align with internal equity. To help start the conversation, the current salary for this role is $20/hr in Mississauga. If the role is available in other locations, the range may differ to reflect local market factors.

Our special culture shines through when we have the opportunity to connect in person. That’s why we’re working in a model where teams are required to be together in the office 5 days per week.
