Oshawa Earth Hour

The Oshawa Environmental Advisory Committee (O.E.A.C.) invites you, your family and friends to attend Oshawa's Earth Hour Event on March 28, 2015, 7:00 p.m., at the Regent Theatre, 50 King Street East, Oshawa.

This fun evening will include presentations and displays with information on what you can do to reduce your greenhouse gas emissions and save money on your energy bill. The evening will also feature a screening of the film "No Impact Man”, and prizes for the best eco-tips.

Light refreshments will be provided, along with a cash bar. Admission is FREE. Donations of non-perishable food items will be accepted.

If you are unable to attend the Regent Theatre event, the O.E.A.C. reminds everyone to turn out their lights and other non-essential power during Earth Hour – 8:30 to 9:30 p.m.

Carbon Reduction Challenge

The O.E.A.C.'s Carbon Reduction Challenge will be launched during the Earth Hour event on March 28, and will continue until Earth Day, April 22.

 Daily challenges will be posted on the City’s website, along with Twitter (#OshEco) and Facebook.

The O.E.A.C. is working with its partners at U.O.I.T., Durham College and the Oshawa Public Libraries to spread the word about how committing to small daily challenges can add up to big savings – both for your wallet and the environment.

The Oshawa Public Libraries will be collecting your creative ideas on how to “reduce the juice”, as well as provide information and resources to help you with the daily challenges. At the end of Challenge, the best tipsters will win eco-friendly prizes.

Eco-tips can also be dropped off at Service Oshawa, 50 Centre Street South, or emailed to
