Salmon Migration in Mississauga: Witnessing a Journey of Survival and Resilience

Mississauga – Each fall, Mississauga’s Credit River transforms into a natural spectacle as freshwater salmon embark on their annual migration, known as the salmon run. As temperatures cool and rain-fed waters deepen, these determined fish swim upstream from Lake Ontario, fighting against natural obstacles to reach their spawning grounds.

This seasonal event, which peaks in early October, offers residents and visitors an incredible opportunity to witness one of nature’s most arduous yet inspiring journeys.

Get ready! Salmon migration season is now underway.

A Struggle Against the Odds
The salmon run is more than just a migration; it’s a life-or-death journey. After spending their lives in Lake Ontario, mature salmon head upstream to spawn and lay eggs. For many, this will be the final chapter of their existence. Chinook salmon, one of the three species found in the Credit River, typically die after completing this journey. In contrast, Atlantic salmon return to the lake after spawning, while Coho salmon also make the challenging trip upstream.

Witnessing the salmon’s upstream battle can be awe-inspiring, but it’s important for spectators to respect the process and avoid disturbing these fish in their critical moment.

Where to Watch
Mississauga has several prime locations to observe the salmon migration:

• Meadowvale Conservation Area: Located in the city’s north, this serene spot features a pedestrian bridge that provides a perfect vantage point to watch the salmon swim up the Credit River.
• Barbertown Bridge (Streetsville): This quiet pedestrian bridge is a great place to watch salmon “stage” – a process where they rest and feed before their final push upstream.

Due to summer rainstorms in 2024, some trails have been closed for safety, but these spots remain accessible for viewing.

Respecting the Salmon’s Journey
Watching the salmon run is an unforgettable experience, but it’s essential to do so without adding stress to the fish. Spectators can help ensure the salmon’s survival by following a few simple guidelines:

1. Watch from a distance: Avoid standing in the river or disrupting the water. There are plenty of safe viewing spots along the banks where you can capture stunning photos without interfering.
2. Track the salmon online: The Toronto and Region Conservation Authority (TRCA) offers real-time updates on the salmon’s progress. You can even report sightings to help others plan their visit.
3. Keep it clean: If you’re snacking while watching, be sure to dispose of trash properly. Littering can harm the ecosystem and the fish.
4. Maintain silence: Noise can stress the salmon, so it’s important to keep the area quiet and avoid throwing objects into the water.

Know Your Salmon
Not all salmon look the same, and knowing the difference between species can enhance your viewing experience:

• Chinook salmon: These fish can grow up to 100 cm and typically die after spawning.
• Atlantic salmon: Unlike Chinook, they return to Lake Ontario after their migration.
• Coho salmon: These smaller salmon, native to the North Pacific, were introduced to the Great Lakes in the 1960s and can grow up to 75 cm.

The offspring of these species will hatch in the spring and eventually make their way to Lake Ontario, only to return years later to complete their own migration.

Fishing Regulations
While fishing is a popular activity in the Credit River, it’s important to note that salmon fishing season ended on September 30. It’s illegal to net fish during the migration, and those caught violating the rules can face fines.

Don’t Miss the Run!
Salmon migration season is now in full swing, and most fish will have completed their journey by the end of October. For those eager to witness this natural phenomenon, now is the time to visit Mississauga’s riverside parks.
