Gail Krantzberg spent decades working on Great Lakes policy and protection — years before this whirlwind year of politics on both sides of the Canada-U.S. border crept into the ways the lakes are protected. 

In Canada, U.S. President Donald Trump’s ongoing trade war has seen federal and provincial legislation introduced in the name of national sovereignty, with major implications for the land, water and air. Now, Trump has given Lake Ontario a new name — at least for the purposes of the U.S. federal government and a couple online mapping services — like Google — that (controversially) followed suit. 

But changing the name doesn’t change the international boundary running through the lake. Nor does the executive order change the agreements and institutions developed by Canada and the United States to manage their shared waters, Krantzberg said.

Krantzberg, now a McMaster University professor, previously served as director of the Great Lakes regional office under the International Joint Commission, an independent organization established by the two countries more than a century ago to resolve disputes over transboundary waters.

Lake Ontario’s name dates back to the 17th century and comes from the Wendat word Ontarïio’, which means the lake is beautiful and great. It’s a part of the Great Lakes system where pollution, invasive species and the effects of a changing climate don’t stop at an international boundary. Protecting the lakes has long depended on governments, scientists and communities on both sides of the border working together.

The framework for that co-operation dates back to the 1909 Boundary Waters Treaty. The treaty set out how the U.S. and Canada would manage shared waters, including the Great Lakes.

That co-operation expanded in the 1970s as serious pollution problems emerged in Lake Erie. High levels of phosphorus contributed to major algae growth and fish deaths, prompting Canada and the United States to sign the Great Lakes Water Quality Agreement in 1972. The agreement was updated in 1978, 1987 and again in 2012. It sets shared priorities for protecting the lakes, including controlling invasive species, reducing agricultural pollution or responding to the effects of climate change.

Amidst everything else going on, many people are questioning what, if anything, Lake Ontario’s name change actually means for the Great Lake and the many transboundary efforts to protect it. Here’s what Krantzberg had to say.

This interview has been edited for length and clarity.

What are your biggest concerns about Lake Ontario right now, in light of the Trump administration changing its name — particularly when it comes to environmental protection and governance?

The name change is, in a way, a distraction from what’s actually happening to the lake. So we start worrying about the name change, and how he can do that and about hundreds of years of history of native naming of Ontario. There’s all this conversation, but it steers the conversation away from what Trump is actually doing for Ontario and all the Great Lakes. 

He’s pro-deregulation. Air emissions from coal-fired utilities, for example, continue to put out more mercury, and that mercury gets into the Great Lakes, the fish and the wildlife or humans that consume them. 

The pushback on banning and phasing out of very persistent chemicals like perfluorinated chemicals or PFASs — some people call them forever chemicals. These things will last in the Great Lakes for centuries, they basically do not break down. They have very detrimental effects on the health of humans as well as wildlife.

The cutting of monitoring — atmospheric monitoring, surveillance monitoring for weather forecasting and climate change modelling — puts not just our understanding of how the lakes are going to behave, but actually shipping at risk. We need to be able to forecast severe weather events so that cities can protect their drinking water for their people and shipping can be protected. 

The cuts to the National Oceanic and Atmospheric Administration (NOAA) are really very, very serious. In fact, its Great Lakes Environmental Research Laboratory was cut by about 35 per cent. You lose the capacity to monitor and understand the lakes, and if you can’t understand the lakes, you can’t protect the lakes.

Beyond changing the name on U.S. maps and federal documents, does this have any practical effect on jurisdiction over Lake Ontario?

No. The only thing that that rename applies to is U.S. federal agencies and institutions. Of course, Trump has managed to get Google and Amazon and others to change their map online. If you go into the map online in the states, you’ll see Lake America. If you go to Canada, you’ll see Lake Ontario. If you go internationally, you’ll see both. 

But frankly, it’s the same body of water and it’s governed the same way. The states do not have to pay attention to it. In fact, we’ve heard the New York State governor say it’s Lake Ontario. Our prime minister and our premier said it’s Lake Ontario and it will always be Lake Ontario. 

In the states, certain federal administrations have to abide by the president’s order. It only applies to their name of Lake America. We don’t know yet, but it should not apply to how it’s managed or the nature of the challenges and threats to the lake.

Does either country have the legal ability to unilaterally assert greater control or jurisdiction over Lake Ontario? If so, what are the limits?

There is no way. Any control is only in terms of control of levels and flows of the lakes. So we can control the levels and flows just to protect commerce, people and ecosystems. For various reasons, we need to control levels and flows and that responsibility lies with the International Joint Commission. It is not driven by a desire by Canada or the United States to do one thing or another.

That said, nobody, no one really controls the lakes. That’s a massive piece of water — you can’t control that. What you can do is make it better or worse on your side of the border. And what we’re worried about right now is that it’s going to get worse on the U.S. side of the border, which means since the water goes all through the system, it will get worse on the Canadian side. One country cannot protect without the other country protecting.

Could a move like this affect the long-standing system of collaboration and shared management between Canada and the United States?

The name of the lake is only about how Trump and Ford don’t like each other, and so Trump said, ‘You know what, bully Mr. Ford. I’m not going to call it Ontario because I don’t like Ontario, so I’m going to call it America.’ That’s all that that is. 

This whole thing about American federal scientists in the United States having a censor happened well over a year ago. I remember getting invited to a conference where this particular invitation said, ‘If you are U.S. federal scientists, check with your administration whether you can attend because this is an international gathering.’ So that was a warning. It’s an international gathering. You may not be able to come and share your knowledge because you’ve been told you’re not supposed to share. 

Now, I don’t know what the rationale is behind that because we’ve always shared information. We’ve always shared science. In fact, when we monitor the Great Lakes, we coordinate surveillance and monitoring. A lot of that monitoring data is now not available to a lot of Canadian scientists who collaborated with the National Oceanic and Atmospheric Administration on hydrological modelling to understand climate change in the Great Lakes.

I believe co-operation on both sides of the border will continue. And I’ll say this because we have the Conference of the Great Lakes St. Lawrence Governors and Premiers. They are motivated to work together as a unit, regardless of country. The Great Lakes are a precious resource for their economy, for their social well-being, for their culture and for their people. They continually work on projects and programs to build, strengthen and protect the economy of the Great Lakes region, which is a multitrillion-dollar economy.

That co-operation and collaboration at the governor level is happening. At the mayor’s level, it’s happening. The Great Lakes St. Lawrence Cities Initiative has more than 400 mayors from both sides of the border. They’re passing resolutions on what they will do collectively to protect the waters of the Great Lakes for their shared benefits. 

The only collaboration that will be paused — and I think that’s the right word — is collaboration with U.S. federal scientists. But there are a lot of other scientists in the U.S. that collaborate with Canadian scientists, and that continues. 

But the overall collaboration, we’ve seen before. We saw when Trump came in and wanted to destroy, zero out funding for the Great Lakes Restoration Initiative, which is a $300-million or so initiative to restore degraded areas around the Great Lakes. The governors said no way. The governor stopped them. It didn’t matter if they were Democrat or Republican. They said that’s jobs, that’s the environment, that creates wealth, that creates beauty in our waterfronts, that increases property values, that’s tax revenue. Like, hands off. This is not frivolous tree-hugging stuff. This is restoration of waters and of well being, and they stopped that.

Do you feel there has been a gap in coverage or public understanding of what this name change actually means for Lake Ontario?

There’s a lot of anger. There’s some people who laugh. You can call it what you want. It’s still Lake Ontario. 

But I would hope that the focus is on how we all work to ensure the lake stays protected. How do we ensure we do what we can, even as individuals, to do our part to be stewards for the lakes?

One of the messages that I’m hoping will come out of all of this is let’s not get distracted by a name change that will eventually be reversed anyway. Once Trump is gone, it’s not going to stick. That’s my prediction. I could be wrong. Let’s not get distracted by a political jockeying of position and power mongering. Let’s focus on what’s important, and that is the health of the Great Lakes.
