Toronto Works and Emergency Services was a former City of Toronto department that was responsible for a variety of services including water and sewage, solid waste management, and snow removal.

The department took over public works departments from the former cities of Metro Toronto, as well as waste management portion of Metro Toronto Works.

In 2002, the city launched a review of water and waste water matters, which recommended the creation of a municipal service board. However, this was strongly opposed by the public and it was recommended instead that the Water and Wastewater Services Division become a unit within the department of Works and Emergency Services.

The department was organised into two divisions:

Initially, the division reported to a deputy city manager but, with the appointment of a new executive committee^{[clarification needed]}, the division came to report to chair of the Public Works and Infrastructure Committee.

The department had responsibilities for a number of services, including:

Toronto maintained a network of water filtration plants, pumping stations and reservoirs providing water to the city. Some facilities were located outside the city, with two reservoirs and one water tank located in York Region. Sewage treatment facilities were located along Lake Ontario to treat water from households and industry and commercial consumers before there were released into the lake, while sludge was sent to dumps and other facilities in the province.

The department also spearheaded public works projects to, amongst other things, repairs sewers, manage water networks, and maintain city facilities. For example, in 1999, Toronto piloted front-loading washing machines in public housing to assess water and energy savings. Toronto's Works and Emergency Services Department partnered with industry (including Maytag Appliances, Enbridge Consumers Gas, Procter & Gamble and Harco Company) and the Toronto Housing Company.
