Heavy snow is causing widespread power outages in regions across Quebec, according to Hydro-Quebec on Tuesday. “Wet, heavy snow combined with strong winds has weakened vegetation, which is falling onto the network,” the Crown corporation states. “We are mobilizing the necessary teams to restore service as soon as possible.” Hydro-Quebec says it has 800 people on the ground to restore power as soon as possible. “This snow comes in a little early this year, and there are still quite a few leaves on the trees that make the heavy snow,” Hydro-Quebec’s Cendrix Bouchard told Andrew Carter with CJAD 800. “The snow we’re receiving is very wet and heavy. It causes the branches and the trees to lean on the network. That’s what’s causing those outages.” According to Environment and Climate Change Canada (ECCC), about 20 cm of snow fell in downtown Montreal overnight.
