Right on the border
Did you know that I’m in Québec, but my spillway is in Ontario? It’s true! The river serves as the border between the two provinces.
Laurentides, QC
You may think I'm pretentious, but I’ll say it anyway—I’m a landmark! I’m the first hydropower generating station in the province to have been built under the supervision of French‑Canadian engineers. You could even say that I marked a turning point in the history of electricity in Québec.
Located in the Laurentides region, I’m a beautiful run‑of‑river generating station, near Long‑Sault, site of the historic battle between Iroquois and New France settlers. I’m on the Rivière des Outaouais (Ottawa River), which forms a natural border between Québec and Ontario.
But that’s all I’ll say for now. If you come see me, my guides will reveal all (almost!) of my secrets. Here’s a tip: After your tour, be sure to hop over to see the Canal‑de‑Carillon National Historic Site. It’s right next door! You can observe the boats using the locks and have a picnic nearby.

I was built and managed by French‑speaking engineers, a first for that era. My construction site provided an opportunity for many French‑Canadian students and employees to acquire solid experience. They met this major challenge brilliantly. The proof is that I was commissioned on schedule in 1964.
I’m the 17th and last generating station on the river to generate electricity. The fact remains that I’m the most powerful of all: I can supply 150,000 homes with electricity!
The river has a mean flow rate of 2,000 cubic metres per second and can reach up to 8,000 cubic metres per second during the spring freshet! No matter—My Kaplan turbines can adjust the angle of their vanes to the quantity of water.

My construction marks a turning point in the history of Hydro‑Québec and, in a way, in the rise of Québec consulting engineering. In the wake of the Quiet Revolution, when a current of francization quickly spread to Hydro‑Québec and all its construction sites, I was the first hydropower generating station whose construction was entrusted to French‑speaking engineers.

1944: First phase of electricity nationalization in Québec
The hydraulic potential of the sector had been exploited since the beginning of the 20th century. In 1943, Québec and Ontario agreed to share hydraulic power from the Rivière des Outaouais, the border between the two provinces. As part of this agreement, Québec obtained the high‑potential Carillon rapids. Construction began in 1959.

Don’t take our word for it: this is what the people who visited the generating station with our guides had to say.
Thank you for offering these tours. They teach a lot about how a hydropower generating station works. Captivating!
Marie‑Noëlle is a fantastic guide. She makes good use of the materials when she explains things. Congratulations!
The generating station is worth the visit. Everyone should tell other people to come, too.
