A funeral is scheduled for Sunday for a 54-year-old Ottawa man killed in a downtown crash that has since led to impaired driving charges.

Ottawa police say Alain Seguin was driving south on Bank Street near Laurier Avenue West just before 4 a.m. Wednesday when his Kia Rondo was struck by a Honda Civic.

Police had been following the Honda so Ontario's Special Investigations Unit is investigating.

Adam Patrick Prevost, 19, now faces three charges including impaired operation of a motor vehicle causing death, criminal negligence causing death and failing to provide a breath sample.

The charges against Prevost allege he was “driving at a high rate of speed” and ran a red light before the fatal crash.

Prevost appeared in court Thursday and was released from custody on the condition he stay at his home and observe a curfew, not contact the other teen he was driving with, abstain from any drugs or alcohol and not operate a motor vehicle. He also posted a $10,000 bond.

Police said Seguin was found with vital signs absent and taken to hospital, where he was pronounced dead soon after.

Seguin was engaged, had two daughters, two stepdaughters and three grandchildren, according to the obituary posted online. His Facebook page also showed he was into classic cars.

Donations to MADD Ottawa

Two visitations are scheduled for Saturday from 5 p.m. to 7 p.m. and Sunday from 11:30 a.m. to 1:30 p.m. at Hulse, Playfair & McGarry funeral home at the intersection of McLeod and O’Connor streets.

The funeral is set for 1:30 p.m. Sunday at the same funeral home.

Seguin’s family encourages all donations be made to MADD Ottawa, according to the obituary.

The crash on Wednesday closed a busy area of downtown from the early morning until after the afternoon rush hour, affecting vehicle, bike and pedestrian traffic from all directions. It also damaged the Shoppers Drug Mart at Bank and Laurier.
