Ontario plans to reduce the number of conservation authorities from 36 down to seven.

These authorities monitor water levels and erosion, manage recreation, teach people about the environment and more.

In a statement, the government said more than half of municipalities fall under two conservation authorities, making situations more difficult for them.

“Right now, Ontario has 36 conservation authorities operating largely on their own, with fragmented and outdated data systems and a patchwork of standards and service delivery,” said Environment Minister Todd McCarthy on Oct. 31.

Its current plan wouldn’t cut out all of the duplication: the province writes that about 63 per cent of the overlap would be reduced.

The proposed changes would be more efficient for communities, the province said, while keeping the same funding and mandate.

There are environmental concerns about what the consolidation will mean.

“No one wants inefficiency, but I think everyone wants permits to be issued in a way that does protect people, their homes, their businesses from risks,” said Tim Gray, executive director of Environmental Defence.

“As we know with climate change and the rain events that we get more and more, they’re more and more intense.”

He said the proposals could mean less access to expert knowledge around flood risks, human health and where to build.

The detailed plans have been posted for public comment until late December.
