In Brampton, the case that ended four lives has moved another step through the courts. An Ontario court has dismissed the appeals filed by Brady Robertson in the 2020 fatal crash that killed teacher Karolina Ciasullo and her three daughters, Klara, Lilianna and Mila Ciasullo.
The ruling, issued by the Court of Appeal for Ontario on Tuesday, keeps the focus on a crash that has already been examined through conviction, sentencing and constitutional challenge. For the family and for the public watching the case, the decision closes one more avenue of legal dispute while leaving the loss unchanged.
What did the Court of Appeal decide in the Brampton case?
The court dismissed Robertson’s appeal on conviction and sentencing. Chief Justice of Ontario Michael Tulloch said the THC limit in Canada’s law is constitutional, writing that it is neither arbitrary nor overbroad. He added that Robertson had not met the high burden required to show overbreadth.
Robertson had filed his appeal in 2022, only months after his conviction and sentencing. His lawyer argued that the trial judge was wrong to uphold the constitutionality of the law setting a legal limit for THC blood concentration when driving. Robertson sought to have that part of the law declared invalid and to have his impaired-driving convictions quashed.
The case centers on June 18, 2020, when the crash occurred in Brampton. Justice Sandra Caponecchia found Robertson guilty of having more than the legal limit of THC in his blood. During the trial, she found he had a THC concentration of 40 nanograms per millilitre of blood about 45 minutes after the crash, eight times the legal limit.
Why does the ruling matter beyond one courtroom?
The legal result matters because it keeps in place both the conviction and the sentence in a case that has already become tied to one of the city’s most painful memories. Robertson had pleaded guilty to four counts of dangerous driving causing death in connection with the crash, but pleaded not guilty to four counts of operation while impaired by drugs causing death. The constitutional challenge was rejected in April 2022, leading to the guilty verdict.
His sentence was 17 years behind bars, with nearly three years in credit for time served, bringing the total down to 14 years and two months. In his appeal, he argued that the sentence was unfit and unduly harsh. He said it was disproportionate when compared with other cases, including the 10-year sentence imposed on Marco Muzzo in the deaths of Jennifer Neville-Lake’s three children and father, Gary Neville, in a 2015 crash. Tulloch disagreed, saying the comparisons did not establish demonstrable unfitness.
How did earlier driving conduct shape the judge’s view?
The record before the court also included a separate crash two days earlier, on June 16, 2020. In that incident, Robertson failed to stop at an intersection and crashed into a barrier. The judge said the impact jolted him out of his slumber and that he sped away to evade police. No one was injured in that crash, but the judge said Robertson was not deterred by previous penalties and that the June 16 incident did not serve as a wake-up call.
That detail gives the ruling a broader human frame: it is not only about one night and one sentence, but about a pattern the court said it had to weigh. In that sense, the Brampton crash became more than a single tragic event; it became the point at which earlier conduct, legal limits and family loss all converged in one courtroom record.
What remains after the appeals are dismissed?
What remains is the finality of a court decision and the continuing absence of Karolina Ciasullo, Klara, Lilianna and Mila Ciasullo. The law has answered the appeal, but it cannot answer the grief that follows such a crash. For the people closest to the loss, the ruling does not restore what was taken on June 18, 2020.
And yet, for the public, the case leaves a clear marker: the Brampton crash now stands with its convictions and sentence intact, its legal challenge rejected, and its facts firmly on the record. In a city still linked to the scene of that morning, the name Brampton carries the weight of a court decision and the memory of a family that never came home.
