Why Ottawa’s famed Rideau Canal has turned bright green

Experts blame a long hot summer for the algae bloom that is turning Ottawa’s famed Rideau Canal bright green, Global News reported.

It’s not unusual for bodies of water to turn green but it usually happens in the spring and fall, when algae get an abundance of nutrients, says UBC professor Maite Maldonado (at 1:15 mark).

“The conditions in the water are right so they are happy and they start dividing and making many many cells,” she said.
