Toronto is set to significantly expand its Deep Lake Water Cooling (DLWC) system, a sustainable initiative that harnesses the cold waters of Lake Ontario to cool buildings in the downtown core. The expansion aims to provide environmentally-friendly cooling to more commercial and residential buildings while reducing the city’s reliance on energy-intensive air conditioning. By using the naturally cold waters of the lake, the DLWC system helps cut greenhouse gas emissions and decreases the need for traditional refrigerants that contribute to global warming. The expansion will further reduce the city’s carbon footprint and align with Toronto’s broader climate goals, including its commitment to achieving net-zero emissions by 2050.
The expansion is not only an environmental victory but also an economic one. It is expected to create jobs in the construction and energy sectors, while also making energy costs more predictable for businesses in the affected areas. By lowering energy consumption and promoting energy efficiency, the system will help reduce long-term utility costs for businesses, offering a competitive edge for companies operating in Toronto. Furthermore, the project underscores Toronto’s commitment to innovation and sustainability, enhancing the city’s reputation as a leader in green technology and climate resilience. The expansion promises to benefit both the environment and the local economy for years to come. More
