The intensity of the fast-moving river swept the vehicle downstream about two kilometres toward a bridge at Line 109 and Tenth Line to its resting point.

Nancekivell told CBC News that"it's an ongoing police investigation." He said the OPP are searching for the child with a helicopter, a dive team, a drone and other search-and-rescue responders.

Downstream alerts

The flooding is expected to get worse downstream from Brantfordlater today, in places like Cayuga and the Six Nations reserve.

Reports of flooding stretched across southern Ontario, including London, Waterloo, Cambridge, Dunnville, St. Marys, Chatham-Kent and Orangeville.

Officials said iceis blocking water and forcing the heavierflows to find ways around the jams.

In Six Nations, the elected council called a state of emergency late Wednesday afternoon.

Residents along744 West toBatemanLine were most vulnerable, the council said.

"Please note that the current flood conditions are not typical of Six Nations of the GrandRiver Territory," the council said. The highest water levels are expected to occur overnight Wednesday.

Six Nations fire officialsalso closed roads: Fourth Line from Seneca Road to BatemanLine, and Mohawk Road to Third Line. The council is monitoring water levels around the ChiefswoodBridge.

Brantfordevacuation orders

In Brantford, anemergency announcement Wednesday morning noted there is ongoing flooding in the neighbourhoods ofHolmedale, Old West Brant and Eagle Place. Anyone living in those areas was urged to evacuate their homes.

"It's important to keep in mind the levels are very much tied to the ice jam," said Grand River Conservation Authority engineering director Dwight Boyd.

"How it erodes or releaseswill determine how quickly levels will recede."

He said levels were stable as of 11 a.m. but that they would remain high through the day and into tomorrow.

Police wentdoor-to-door in the affected neighbourhoods,asking peopleto leave immediately. Up to 4,900 residents live in the evacuation area.

"Buses are available to help evacuate @ Eagle Ave & Foster St., Baldwin & Erie Ave, Erie & Aberdeen Ave. Those requiring shelter can go to Woodman Comm. Centre," the tweet advised.

Jeff Whitbread was one of the residents who left his home. He told CBC News that the process seemed to be handled well.

"The police and services have been around our neighbourhood and talked to all the residents and its very calm. It seems to be pretty well organized.

"We're just going to pick up a few things and head on out to a friend's house."

The Grand River Conservation Authority said Wednesday morning "an ice jam upstream of Parkhill Dam released at approximately 2 a.m. Wednesday morning. When this ice jam released, it sent a surge of water downstream."

Province 'ready to provide support'

Ontario Premier Kathleen Wynnetoured the area on Wednesday and said the province is "ready to provide support."

"I think it works the best when the municipality lets us know what's needed so we can respond appropriately," she told reporters at the Brantfordfire hall.

Wynnealso said the Ministry of Transportation will inspect city bridges on Thursday and assessif they will remain closed.

Deputyfirechief AndrewLillico said the city is "not out of the woods" yet, as a second swell is expected mid-morning Thursday when more water comes down from theNithRiver, which feeds the Grand.

At least 25 families will be spending the night at a local community centre, said Maria Visocchi, Brantford's director of communications.

"We are overwhelmed by the generosity of the local community in terms of food and water and toys and supplies for the children that are there," Visocchi said.

'You certainly don'twant to see anyoneget hurt'

The agency warned the public in a post on its website to exercise extreme caution around all water bodies.

"Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which will be extremely unsafe as a result of the warming trend."

Frielsaid a dike system put in place in the 1980s prevented a much worse situation.

"This would already be a disaster in our community if we did not have the dikes that are in place."

Robert Putt, a resident in the evacuation area, said he woke up around 2 a.m. to the sound of trees breaking and snapping. When he got up this morning the water level had increased by about a metre.

"You're hoping not to lose property or value or have things damaged, you certainly don't want to see anyone get hurt," he said.

Putt said he's lived in his house for almost 30 years and has never seen flooding like this.

"It's a large amount of water and large amount of ice."

The following schools are closed because of the flooding:

• Princess Elizabeth.
• Agnes Hodge.
• Jean Vanier.
• Bellview.
• Ecole Dufferin.
• Ste Marguerite.
• Ste Marie.
