A Brampton truck driver will be sentenced next month related to a crash that killed an Amherstburg mom and son last summer.

Manjit Parmar, 52, pleaded guilty to two counts of dangerous operation of a motor vehicle causing death and three counts of dangerous operation of a motor vehicle causing bodily harm in Chatham provincial court on July 4, 2018.

Parmar was charged after the OPP say his westbound tractor trailer collided with five vehicles that had stopped on Highway 401 near Dillon Road due to a separate motor vehicle collision on July 30, 2017.

One of the vehicles involved was a Chevrolet Sierra pick-up truck carrying four passengers.

Two passengers traveling in the pick-up, Lacie Brundritt, 42, and Kyle Brundritt, 14, of Amherstburg, were pronounced dead at the scene.

Court heard both were killed instantly in the crash, and Parmer “did not apply the brakes or attempt to stop" when he came upon westbound traffic that was stopped ahead of him.

Lacie’s husband Michael, who suffered a broken back, and younger son Evan were transported to hospital with non-life threatening injuries.

"I offer forgiveness," Michael Brundritt said to Parmar in court on Tuesday. Brundritt also admitted that he feels helpless, disconnected and suffers from a driving phobia.

Kyle Brundritt's girlfriend also read a statement, saying “you're not supposed to bury your boyfriend when you're a teenager.”

The Defence and Crown submitted a joint sentence request of 18 months in jail, followed by 12 months probation.

Defence lawyer Allen Gold argued this comes down to a few seconds of not paying attention and shouldn't be viewed as a serious criminal offence.

He's asking Justice Paul Kowalyshyn to take into account Parmar's guilty plea, his spotless driving record in 17 years as a truck driver and the fact Parmar does not have a criminal record.

Parmar did not offer a reason for why he wasn't paying attention that day. He also stood up in court Tuesday and said “I'm sorry for the family for the loss.”

Parmar is expected to be sentenced on Oct. 10.
