Ottawa paddlers who frequent the Rideau River, Ottawa River, and Gatineau Park waterways have every reason to pay attention to a new policy unfolding in Canada's national parks out west.
Parks Canada has announced restrictions on paddling in certain rivers and lakes within Jasper National Park and other Alberta parks, citing the urgent need to prevent the spread of aquatic invasive species. The move has sparked debate among paddling communities across the country — but most agree the underlying threat is real and serious.
What's the Concern?
Aquatic invasive species — including zebra mussels, spiny water fleas, and various invasive plants — spread primarily through watercraft and gear moving between water bodies. Once established, they can devastate native ecosystems, outcompete local species, clog water infrastructure, and permanently alter the character of a lake or river.
Zebra mussels, in particular, are already a known threat in Ontario and have been detected in several lakes within a few hours of Ottawa. The Great Lakes have battled the species for decades, and the fear is that careless movement of gear between water bodies could introduce them into cleaner, more pristine systems.
Paddlers React — With Reluctant Support
While some paddlers have voiced frustration with the new restrictions in Jasper — especially those who have paddled those routes for years without incident — many within the community are urging compliance. The consensus among paddling organizations is that short-term inconvenience is a worthwhile trade-off to protect waterways for future generations.
The restrictions are targeted, not blanket bans, focusing on specific high-risk waterways where invasive species pressure is greatest or monitoring capacity is limited.
What This Means for Ottawa Paddlers
Ottawa sits at the confluence of the Ottawa River and Rideau River, two of the most paddled waterways in Eastern Ontario. The Rideau Canal — a UNESCO World Heritage Site — draws kayakers and canoeists all summer long. Gatineau Park's lakes are similarly popular.
The "clean, drain, dry" protocol has long been recommended by conservation authorities in this region: clean all gear of visible plant material, drain all water from watercraft, and dry equipment thoroughly before entering a new water body. It's simple, effective, and increasingly critical.
Local paddlers are encouraged to check the Ottawa Riverkeeper and Ontario Federation of Anglers and Hunters websites for up-to-date guidance on invasive species threats in Eastern Ontario waterways.
The Bigger Picture
Canada's national parks are often the first line of defense when it comes to ecological protection — and when Parks Canada moves to restrict access, it's a signal that the threat level has escalated. For a country where lakes and rivers are woven into national identity, protecting them from invasive species isn't a niche concern. It's everybody's responsibility.
Whether you're launching a kayak on the Rideau or planning a canoe trip out west, the message is the same: your gear could carry more than you think.
