The Green Line, in short…

The Green Line: Green Roof started in 2009, when Patrice Godin and Antoine Trottier met along different environmental projects while at UQAM, among which one of them was prize-winner in Force Avenir 2008 and 2010.

After the publication of ‘Toitures végétales en milieu institutionnel: Étude de cas UQAM’ (Green Roofs in Institutional context: UQAM Case Study) by Antoine, they both saw the opportunity to launch their business in that still emerging field in Montreal.

In the beginning named Ligne verte: Éco-conseillers s.e.n.c., it became The Green Line: Green Roof in 2013, after 4 years of green roof, landscaping, green wall and urban agriculture projects.

Now with many projects under the belt over the years, The Green Line: Green Roof is now a leader in the green roof industry.
