The search for a one-month-old child missing in a Laval, Que., river has been paused overnight.

Police say the search will resume Sunday morning, two days after the vehicle in which the infant was travelling drove into a river in Laval, Que.

Earlier in the day Saturday, city police spokeswoman Erika Landry said provincial police divers and a helicopter joined the search, supplementing boats from the local fire department.

People who live along the Mille-Îles river, which divides the island city of Laval from the mainland to the north and east, are being asked to look for the boy along the riverbanks, she said, adding that the current may have carried him several kilometres.

Police still have some hope that the baby will be found alive, said Landry.

"Of course, we have a little hope, unfortunately, the time is against us, the more time passes, the more the chances go down," she said in an interview Saturday. 

The boy was in a vehicle with his mother and four-year-old sister when it plunged into the river shortly before 5 p.m. on Friday.

The woman and the girl were rescued, Landry said. The woman, who is in her 30s, remains in hospital, while the other child was released Friday evening.

Landry said police don't know why the vehicle entered the water and violent crime investigators will meet with the mother when her health allows.
