Thats correct. As of March 2016, the Ministry of the Environmental no longer requires a Permit To Take Water for construction projects. This is huge for construction projects and environmental remediation projects in Ontario. There will be no more lengthy delays for construction projects (including environmental remediation projects that require dewatering). Often times excavations require dewatering due to sudden thunderstorms or groundwater filling. Dewatering an excavation is required for foundation construction or even just backfilling. See the link below to an article by Simon Gautrey summarizing the new regulation.
MOE Permit to Take Water-2016April28_article1
Permits to Take Water require an Environmental Compliance Approval (ECA) formally a Certificate of Approval (C of A) that usually takes months to obtain, so this is a big step forward in terms of lessening the administrative requirements for construction (and environmental remediation) projects in Ontario.
However, a permit to discharge will still be required. Discharge of water is a whole different thing. It requires permitting with the local Regional Government in charge of regulating the discharge water to storm and sanitary sewers and ultimately the sewage treatment plants.
