Ten migrant workers from Peru and Jamaica were killed when a truck hit a passenger van in rural Canada on Monday afternoon, officials said.
The truck driver also was killed. The crash was the deadliest in Ontario since 1999.
Some of the migrant farm workers were from Peru and some were from Jamaica, said provincial Labour Minister Linda Jeffrey.
Three people in the van survived. Police said one was airlifted to a hospital with life-threatening injuries, and the other two were seriously injured.
"On behalf of 13 million Ontarians, I want to offer our deepest condolences to those who lost a loved one and to offer our most sincere prayers for those taken to hospital," Premier Dalton McGuinty said in a statement.
No names of the victims have been released. Albert Burgers, who owns the farm where the workers were Monday before the crash, said some had been with his crew for more than 10 years.
Police told the CEO of the truck company, Speedy Transport, that the van apparently went through a stop sign and was hit by the truck.
The impact sent the van hurtling across a lawn before smashing into a house. The van's passenger side was nearly ripped off.
