    A vision driven by passion.

    Groupe Sierra was founded by Ghyslain Octeau-Piché and Gabriel Dupuis, two real estate and outdoor enthusiasts. They naturally brought their dream to life in Lanaudière, a vast natural playground ripe for adventure and investment.

    Surrounded by trusted partners who share their values, they reinforce a strong commitment to quality and environmental stewardship.

    “Building a living environment is more than raising walls.
    It's creating a place that helps the people who live there grow.”— Ghyslain Octeau-Piché, Co-founder
