River runs through it
Workers with Quebec's Environment Ministry have been excavating a part of the Lake of Two Mountains since July.
The Ministry says it needs to do this because the Riviere des Mille Iles, which flows from the lake, has water levels that are too low.
It says cities near the river get their drinking water from it, but that water will run out unless Mille Iles flows faster.
Guy Garand says Quebec should have acted sooner.
The director of of Laval's Regional Environmental Council says the Riviere des Mille Iles has had low water levels since 2001.
Residents of Deux Montagnes are also concerned about the excavation
Dave Caissy lives near the excavation site.
