Greening initiatives and energy performance

Greening initiatives and energy performance

At our Markham and Uxbridge sites, we believe caring for the community goes beyond patient care. It means leaving a positive mark on the surrounding community and doing our part to be good green citizens. We are proud to be an environmental leader in our community.

We are always looking for opportunities to make our organization more environmentally friendly. Our commitment to the environment can be seen throughout the hospital and in a number of key departments including facilities, environmental services, procurement, waste management and sustainable energy.

Our partnership with Markham District Energy is a great example of working with leaders in the industry to use energy more efficiently. Other green initiatives include our LED lighting project complete with scheduled timers, a new reverse osmosis system and state-of-the-art building automation system, all of which promote energy savings and have a positive effect on our environment.
