TCS Green Cup

Since 2005, TCS has hosted an annual eco-competition between the 10 Senior School houses. Throughout the school year, each house undertakes actions that improve the state of the environment and increase awareness of environmental issues and strategies. A trophy and prizes are presented to the winning houses (one day and one boarding house) each spring. Recent winners:

  • 2023 Orchard House & Rigby House
  • 2022 Hodgetts House & Ketchum House
  • 2021 Wright House & Scott House

TCS students are able to gain valuable knowledge and skills when they choose environmentally-themed service learning opportunities. We are able to provide much-needed assistance to our “neighbours” in local parks and nature reserves where we help with tree-planting, invasive species removal, seed-collection, gardening and more. The authentic learning and sense of valuable accomplishment for our students is powerful. They learn how to put their environmental awareness into action.

Students are also able to experience international environmental service trips, such as to The Island School in Eleuthera, Bahamas.

Great Canadian Shoreline Clean-up

Every autumn, Trinity Environmental Action Club (TEAC) organizes a student-led shoreline clean-up of the Ganaraska River in Port Hope as part of the Vancouver Aquarium’s Great Canadian Shoreline Clean-up. Annually, 20 to 40 TCS students participate and over the years they have removed hundreds of bags of garbage and recyclables, improving the aquatic habitat.

Earth Day

Annually since 1971, TCS participates in Earth Day activities each April 22nd. These include tree plantings, guest speakers, garbage clean-ups and hikes. To learn more, visit
