Groupe Lanthier insurances

Groupe Lanthier was founded in 1955 by Roger Lanthier, who then passed the torch to his son Denis Lanthier. In 2009, Dominique Tanguay, the firm’s current President, became a shareholder. In 2017, Guillaume Larosée, current Vice-President, Commercial Lines and Marine Products, also became a shareholder. Thanks to the vision of the 2 shareholders, the vocation that was once more focused on personal and commercial insurance has expanded with a new niche in marine insurance for boaters and nautical businesses. For over half a century, the company has been offering property and casualty insurance products and excellent service to its loyal clientele.

That’s why, instead of limiting ourselves to a single provider and a single solution as traditional agents do, our team works with several trusted insurers to provide you with personalized advice tailored to your specific risk management needs
