A memorial service for Karolina Ciasullo and her children began in the afternoon on June 25 at the St. Eugene de Mazenod Catholic church.
Four white caskets were brought before the altar as mourners spread out in the pews in accordance with physical distancing guidelines.
The service was closed to the public but was livestreamed, and the church had said the audio would be played outside the building.
Ciasullo, 37, was an elementary school teacher with the Dufferin Peel Catholic District School Board. Her daughters were aged six, four, and one.
The crash last Thursday is being investigated by Peel Regional Police, who said details on the charges would be released later today.
The provincial police watchdog is also looking into the incident.
The Special Investigations Unit has said a Peel Regional Police officer had “observed” one of the vehicles involved in the crash before the incident.
The tragedy set off a wave of grief in the community, with officials including Brampton Mayor Patrick Brown and Premier Doug Ford among those offering their condolences.
