By Cristina Senjug, Partnership Manager, Next Level Stormwater Management

Next Level’s Dr. Karen Liu, Green Roof Specialist along with Cristina Senjug, Partnership Manager are honoured to partake as trainers with the annual Earth Tending Green Infrastructure Training program and look forward to the next session in May 2026.

The Earth Tending program by SpruceLab is an initiative for First Nations, Inuit, and Métis Peoples in the GTA, blending Indigenous Knowledge with Western green infrastructure practices through hands-on, land‑based learning. The program builds skills and pathways into the growing green infrastructure sector while strengthening climate resilience through nature‑based solutions.

Part of the training includes a rare tour of CF Sherway Gardens’ North Expansion Green Roof.

Take a minute and enjoy the unfolding spring splendour of CF Sherway Gardens’ North Expansion green roof in the videos taken during the tours over the last couple of years. CF Sherway Gardens’ North Expansion features 9500 square feet of a soilless green roof system supplied by Next Level Stormwater Management and installed in 2014 and 2015.
