Summary

• The North Bay Parry Sound District Health Unit officially stopped testing water at public beaches.
• In place of testing, the health unit is updating public signage to warn swimmers of risks of heavy rainfall, murky water and large numbers of birds congregating — things that deteriorate water quality.
• Researchers and advocates argue beach water monitoring is important, especially as climate change makes cooling off in the water more necessary — and more hazardous, thanks to algal blooms and pathogens.

Kevin Marois wasn’t aware that the health unit spanning North Bay and Parry Sound, Ont., had stopped testing the water at local swimming spots.“I don’t think it’s a good decision,” Marois told The Narwhal after learning about it on a hot June day at Shabogesic Beach in North Bay. “Not having the information on water quality is the main [concern],” he said as he came out of the water, “And we know that there are problems with water quality during the summer.”

There were six harmful algal bloom events in the health unit’s area in 2025, and more than a dozen in 2024.

After announcing its plans earlier this year, the North Bay Parry Sound District Health Unit has officially stopped testing water at public beaches as of this summer. 

In its place, they’re offering public signage, which the health unit says will warn beachgoers to assess risks from recent heavy rainfall, visibly murky water or large numbers of birds in the water — all things that alter water quality and can make swimming unsafe due to high levels of E. coli or harmful algae.

Despite the updated signage, those who study beach water safety in Canada say ceasing testing could impact people’s ability to make informed decisions about safe swimming this summer. 

Meanwhile, researchers have argued a warming climate in Canada, including more severe summer heat waves, means swimmable water for people to cool off in is more important than ever. 

“We see changing climate patterns, we see urban heat island effects, we see heat domes, we see that there’s a tremendous need for community cooling spaces,” said Gregary Ford, vice-president and Lake Ontario Waterkeeper at Swim Drink Fish, an environmental non-profit that advocates for safe, usable water bodies. Its name comes from signs often posted on shorelines in Canada: no swimming, no fishing and no drinking. 

Ford explained that warmer temperatures and extreme weather events — a part of climate change, which is primarily driven by the burning of fossil fuels — also contribute to more harmful algal blooms and other pathogens that affect the health of the water and people who use it.

Health unit says water testing is resource-intensive and too slow

In March 2026, the North Bay health unit, which also covers Kearney, Nipissing and South River, sent a letter to member municipalities saying sampling the area’s 60 public beaches was too resource-intensive, and lab results took three or four days, limiting their usefulness when water conditions change quickly. The health unit also argued that the risk of illness from water recreation in the region is low. The water was only tested about three times each summer, it said.

Last year, Public Health Sudbury and Districts, a region which includes Manitoulin Island and French River, ended routine water sampling as well — one of many cuts made after the medical officer of health said their funding has not kept pace with inflation.

“Obviously, there are growing pressures on municipalities and public health units … and so we understand that compromises have to be made, but not in something that affects public health,” Ford said. “This is a trend that we see during periods of economic stress and strain … Unfortunately, as these scalebacks start happening, the public is left with less information about their water and, honestly, that becomes the most important part.”

Swim Drink Fish aggregates data from across swimming spots in North America into an app called Swim Guide. But these helpful third-party tools rely on local data collected by public health departments.

“It’s really important that municipalities also provide historical data, even if they’re not sampling today. They should at least publicly make available the data and information that has been collected over the last five years, the last 10 years, so people can still make a somewhat informed decision about where they spend their time,” Ford said. That’s not something made available by the North Bay Parry Sound Health Unit, either.

There are options for protecting beachgoers, but they can’t replace testing: experts

A recent study from Toronto Metropolitan University, which surveyed 4,085 beachgoers at seven beaches in Canada between 2023 and 2025, found that about 2.6 per cent of swimmers reported becoming sick, with children and elderly people facing higher risk of “recreational water illness,” such as stomach issues, ear and eye infections or rashes.

Ian Young, principal investigator on the Canadian Beach Cohort Study, tracking recreational water illness across Canada, said despite that low risk, “having a solid monitoring plan is important to give people confidence in the beach.”

He pointed to other methods being used across the country to help combat the slow, unreliable nature of current testing. For example, at Bluffer’s Park Beach in Scarborough, Ont., the City of Toronto implemented a bird management program, involving removing sources of food and training dogs to spur geese into flight, once they realized a substantial amount of the E. coli in the water at the beach was caused by birds.

Ford, from Swim Drink Fish, has seen other solutions; municipalities like Kingston and Hamilton are trying out new technology that alerts citizens in real-time when sewers and sewer bypasses are overflowing and contaminating beach water. But, he said, this does not replace the need for monitoring.

“It is a far second in terms of a solution. The best solution is to be continuing and continuously monitoring these beaches,” Ford said. “Resources can be stretched thin at times. This is a public health interest, it is a tourism interest and it is an individual health and wellness interest as well. So, this should be a priority for public health units, and it’s disappointing to see some of these decisions that are being made.”

To help mitigate risk, North Bay’s health unit recommends swimmers wash or sanitize hands before eating after swimming, towel off well to help prevent swimmer’s itch, check for hazards before entering the water and avoid getting water in their mouths.

But North Bay resident Ashley Brooker, standing at the shore of Lake Nipissing, said she still doesn’t feel good about the testing changes. “I am a risk-taker, but that doesn’t mean that I want to risk getting sick or catching something,” she said. “Safety is a big thing, and if we’re putting our tax money into something then we should be getting the resources back.”

Summary

• Under the Clean Water Act, community-led groups called source protection committees write plans and oversee the protection of drinking water sources in Ontario.
• The jurisdiction of the committees is aligned with the boundaries of conservation authorities, and experts say the recent amalgamation of authorities could also affect the committees.
• The province has not appointed 15 of the 19 source protection committee chairs, leaving some experts questioning whether change is afoot.

As the Doug Ford government moves to consolidate conservation authorities from 36 to nine, many are concerned about the impact on Ontario’s drinking water. 

Conservation authorities have long been tasked with protecting Ontario watersheds by safeguarding local drinking water sources and reducing the risks from natural hazards like flooding, erosion and drought. But the government’s legislation for their amalgamation — the biggest disruption to the agencies in 80 years — indicates there may be changes coming to the way they help preserve access to fresh water for more than 80 per cent of Ontario residents. 

Since 2006, municipal drinking water has been governed by 19 source protection committees, community-led groups with directors from industries like agriculture, manufacturing and tourism that hold conservation authorities and municipalities accountable for properly managing drinking water. Within each conservation authority, designated staff serve as liaisons to these committees, providing necessary data and carrying out any suggested protective actions.

“Source protection committees are purposefully local. They’re the people that drink the water they are protecting,” Katie Stammler, water quality scientist and project manager for the source water protection committee at the Essex Region Conservation Authority, told The Narwhal.

The committees were created on the heels of the water contamination crisis in Walkerton, Ont. In May 2000, seven people died and some 2,300 people became ill when manure from a nearby farm leached into a well due to a failure of safety checks in the local water treatment system. 

An inquiry into the crisis resulted in dozens of recommendations, including creating source protection committees. These groups were officially enacted by the passage of the Clean Water Act. Each one was designed with the boundaries of conservation authorities in mind and tasked with writing a plan to protect the sources of drinking water in that region from threats such as fuel, sewage, road salt and agricultural runoff.

In the years since they were formed, source protection committees seemed to be “untouchable,” Lynn Dollin, once long-time chair of the South Georgian Bay-Lake Simcoe Source Protection Committee, told The Narwhal. Successive Ontario governments didn’t want to change anything “because no one wants to risk another Walkerton.”But things might be changing now.

The Ontario government’s move to reduce the number of conservation authorities has meant that each authority now covers a much larger area. The Narwhal obtained a government slide deck presented to conservation authorities leaders earlier this month that shows drinking water source protection “remains a core mandated responsibility” for the nine proposed regional authorities, and that source protection plans “will continue to be carried out.” 

But in the same slide deck, the government also notes “changes may be needed under the Clean Water Act and associated regulations” to “clarify” how source protection committees would operate under the new structure. 

“We’re not making any fundamental changes [to source protection committees],” Ontario Environment Minister Todd McCarthy said in an interview with The Narwhal: the 19 committees will remain as they are and work with the nine newly proposed regional conservation authorities, though he said their jurisdictions are “a work in progress.”  

“Clean water is absolutely essential, and Ontario’s is best protected in the world. That’s going to continue,” he said. “The idea is to make sure it doesn’t change by better resourcing and better supporting [them] equally across Ontario.”

McCarthy added that there may be some legislative “housekeeping” in the fall to ensure “alignment” between the new regional conservation authorities and source protection committees. 

The absence of details raises red flags for experts. 

“They cut. Now they cut and tinker,” one central Ontario conservation authority official said. “They’re saying nothing is going to change, but in practice, that remains to be seen. … All the changes they’ve made so far have delayed work operations. They like to pretend otherwise.”

The Narwhal spoke to 12 people, including lawyers, members of three source protection committees and several conservation authority staff, many of whom spoke anonymously for fear of retribution. As conservation authorities get bigger, these experts worry about the loss of local input, knowledge and protections. 

Already, the chair positions at 15 of the 19 committees are vacant. To many, this quiet erosion of leadership and a loosening of water laws in the province are indicators that a system put in place to prevent another drinking water crisis is now in flux. 

Most source protection committees still don’t have government-appointed leaders

Nearly 20 years ago, Dollin, now mayor of Innisfill, Ont., was one of 19 source protection committee chairs appointed by the Ontario government to help take care of the province’s complex system of local drinking water sources.

Back then, her committee’s first task was “a little unnerving,” she said. “I was shocked how there was no good, complete list of where our municipal drinking water systems were.” So they created one, along with guidelines on how to protect them to ensure local drinking water sources don’t become contaminated or overused. 

Dollin’s term as head of South Georgian Bay-Lake Simcoe Source Protection Committee ended in August 2025; she was told by a ministry official she would not be reappointed, though she said no reason was given. Her position hasn’t been filled since. 

As of April 14, the government had not appointed several chairs — something it is legally required to do under the Clean Water Act — since summer 2025.

“The absence of appointed chairs over the past year has created some uncertainty at the committee level, particularly around governance, leadership continuity and decision-making authority,” John Mesman, managing director of property, conservation, lands and community outreach for South Nation Conservation, told The Narwhal. 

A lack of chair appointments, others say, may indicate source protection committees are a low priority amidst the amalgamation of Ontario’s conservation authorities. Many told The Narwhal communication between conservation authorities and ministry staff have been eroding since the government under former premier Mike Harris first cut funding in 1995.

“It seems the ministry doesn’t understand the source protection program, so it doesn’t bother to think about it,” the central Ontario conservation authority staff member said. “We started getting alarmed by ministry decisions a while ago on a number of issues. It’s been consistent, our comments are not being heard.”

That’s especially challenging as water supply gets more complicated. In recent weeks, the government has proposed permitting communal wells for private development. That would mean a new subdivision, for example, could draw from its own well instead of tapping into municipal water services. Sources who spoke to The Narwhal were concerned about this because communal wells aren’t currently overseen by source protection committees. 

“We need source protection leaders now more than ever to be present at the table,” a conservation authority official in western Ontario said. “As this government pushes approvals for development, we need to make sure water is not an afterthought.” 

A Ministry of Environment official told The Narwhal, “a competitive process will soon be underway” for source protection committee chair appointments. 

New boundaries of conservation authorities could affect source protection committees 

Not only do many source protection committees not have leaders right now, but they also don’t know what their jurisdictions will be post-conservation authority amalgamation.

“I don’t think [the government] contemplated a whole scale change like this,” Theresa McClenaghan, executive director of the Canadian Environmental Law Association, said. “A lot of people don’t realize that most local drinking water sources are protected by plans that were created by these committees over many years.” 

Per the requirements of the Clean Water Act, the government has two options, McLenaghan said: realign source protection boundaries and governance to reflect the new larger regional conservation authorities or maintain the current structure within the new regional authorities. 

Minister McCarthy told The Narwhal the boundaries “are not changing at this time,” but the exact boundaries will be finalized in the fall, informed by consultations with new local watershed councils the ministry is creating to facilitate the transition. 

“We’ll have to see how this works out,” he said. “Right now, the reality is nine watershed-based regional conservation authorities are what we proposed … and with those 19 [source protection committees], we’ll have to see how their boundaries match up or align.” 

McLenaghan said if the committees stay as they are, “that’s good news,” but “there will still be some potential disruptions” as several source protection regions combine under a single conservation authority.

Right now, some source protection areas, such as Essex County, stand alone, while others like the Thames-Sydenham Source Protection Region, combine several conservation authority jurisdictions. Per a preliminary analysis by the Canadian Environmental Law Association, the amalgamation would see the inverse of this, where one regional conservation authority has several source protection regions within it. For example, both the Lake Huron and Western Lake authorities would each incorporate three source protection agencies.

The new regional conservation authorities will be “very, very busy” managing so many source protection committees under the new system, the central Ontario conservation authority official said.

Under the amalgamation plan, Stammler’s Essex County Conservation Authority now falls under the Western Lake Erie regional authority, which has boundaries spanning from Niagara through Halton and Peel Region.

She, and others, said they’re concerned this will result in a reduction in the hyper-localized focus on water that conservation authorities provide.

“I think it’s going to undermine Ontario’s ability to protect drinking water,” Ontario Greens Leader Mike Schreiner said. “I think the amalgamation of [conservation authorities] is going to contravene the recommendations of the Walkerton inquiry around source water protection.”“I mean, how can you have 19 source water protection committees across the province and nine [conservation authorities]? And how is that going to work together, especially when you’re undermining local decision-making expertise?”

It’s something local industry representatives are similarly concerned with. 

Chris Snip, an independent agronomist and water protection advocate from Essex County, has built a career helping farmers grow better crops with less impact on the environment from fertilizer use. He joined the Essex region’s source water protection committee six years ago to support the group’s understanding of agriculture and the sector’s role in maintaining water quality.

As with many in Ontario’s farming community, the Walkerton tragedy casts a long shadow for Snip. With the Ford government’s changes to water protection, in favour of easing development, Snip wonders if the province is forgetting lessons of the past.

“People died, and the policies around source water protection were based on recommendations from those deaths and injuries, and this provincial government is basically, you know, turning its nose up to it, not caring about what happened then,” he said.

“History is bound to repeat itself, especially if we don’t remember.”
