Canadair CL-215 loading and unloading water

At the Beauharnois Canal, on Saturday May 21st 2016, there was a forest fire at Saint-Stanislas-de-Kostka, Qc.
We witness the plane doing at least 10 cycles of loading the water and unloading it over the fire near the shore. Each time we saw that plane almost turn on a dime and pass not more than 10 meters over the bridge to get more water.
