There are several federally regulated energy infrastructures located throughout Ontario. If Indigenous Ministerial Arrangement Regulations (IMARs) are made, it could enable the Minister of Energy and Natural Resources to enter into Indigenous Ministerial Arrangements with Indigenous governing bodies (IGB). Through the arrangements, the IGBs could have the authority to exercise responsibilities over the regulatory oversight of energy infrastructure under the Canadian Energy Regulator Act (CERA).
Federally regulated energy infrastructure in Ontario
Text version
This map of Ontario focuses on the locations of major pipelines and powerline terminals regulated by the Canada Energy Regulator (CER). It also shows where First Nation Reserves are located in relation to the energy infrastructure, with some in close proximity to the TC Canadian Mainline and others along pipelines in southern Ontario. Few pipelines are found in northwestern Ontario, the TC Canadian Mainline being the most notable going from the Manitoba border, east towards Timmins and then south towards the Quebec and United States borders. Several pipelines travel from the western to eastern borders, along Lake Erie and Lake Ontario. There are also several powerline terminals in northwestern Ontario, along the Minnesota border. The powerline terminals are found mostly south of Ottawa, at the United States border in Niagara Falls and along the border of Michigan, US. More details about the energy infrastructure can be found in the following tables.
