A countrywide arrest warrant has been issued for a 25-year-old Ontario man accused of driving a semi-trailer truck through a stop sign before a crash that killed a Manitoba mother and daughter.

RCMP charged Navjeet Singh with two counts of dangerous operation of a motor vehicle causing death and one count of obstructing a police officer on Wednesday, police said in a news release.

Efforts to find the 25-year-old from Brampton, Ont., in Winnipeg were unsuccessful, and police say they’ve issued a Canada-wide warrant for his arrest.

Police allege Singh drove a semi through a stop sign on Highway 201 on Friday evening, crashing into an SUV at the intersection of highways 201 and 306, about 13 kilometres west of the town of Altona, Man.

RCMP previously said Singh was taken to hospital, where he was treated for injuries and released.

Anyone with information on Singh’s whereabouts is asked to contact their local police detachment, the Pembina Valley RCMP at 204-822-5469, or Crime Stoppers anonymously at 1-800-222-8477 or on their website.

The crash killed Sara Unger, 35, and her daughter Alexa Unger, 8. They were heading home from the grocery store, family members previously told CBC News.

The two were from the rural municipality of Rhineland, which surrounds Altona, about 90 kilometres southwest of Winnipeg.

Sara was pronounced dead at the scene. Alexa, who was a passenger in the SUV, was airlifted to Winnipeg’s Health Sciences Centre, where she died from her injuries.

A witness to the crash who had been travelling behind the SUV told RCMP she slowed down because she saw the semi approaching the intersection at high speed, Manitoba RCMP Sgt. Paul Manaigre previously told CBC News.
