OttawaOn the fifth of December, 2023, Bill C-48 received Royal Assent, and the law governing who must argue for their own freedom before trial changed in Canada. It changed quickly, by the standards of criminal law, and it changed because of a death. To understand the new bail rules you have to understand the killing that drove them, and to weigh the new rules fairly you have to hold two things at once: that the public-safety concern behind them is real, and that the principle they bend is one of the oldest the Charter protects.

The death, and the demand

On the twenty-seventh of December, 2022, near Hagersville, Ontario, Provincial Constable Greg Pierzchala was shot and killed responding to a vehicle in a ditch. He was twenty-eight. One of the men later charged with first-degree murder in his death had, in a separate matter, been released on bail after initially being denied it, on charges that included assault and firearms offences. That fact, an accused out on bail facing weapons charges, became the engine of everything that followed. The charges against that man were, and at the time of the law's passage remained, allegations to be tested at trial, and the presumption of innocence applies to him as it applies to anyone. But the political effect of the bail history was immediate and did not wait for a verdict.

On the fourteenth of January, 2023, all thirteen premiers and territorial leaders signed a letter to the Prime Minister, drafted out of the Ontario premier's office, demanding immediate action on bail. The phrase that organized the public argument was catch and release: the claim that the courts were freeing dangerous, repeat offenders who then reoffended. Within eleven months, Parliament had answered.

What the law actually did

Bill C-48 works mostly through a mechanism called reverse onus. Ordinarily, when the Crown wants to keep an accused in jail before trial, the Crown carries the burden of showing why detention is justified. Reverse onus flips that: it puts the burden on the accused to show why they should be released. C-48 widened the list of situations where that flip applies. It added a reverse onus for a person charged with a serious violent offence involving a weapon, one carrying a maximum of ten years, who had been convicted of a similar offence within the previous five years. It expanded reverse onus for certain firearms offences and for intimate-partner violence. And it directed courts to consider community safety and an accused's history of violence when deciding on release.

Reverse onus does not change whether someone is guilty. It changes who has to do the arguing, and at the bail stage, before any trial, the person doing the arguing is by definition still presumed innocent.

The principle on the other side of the scale

Here is what an honest accounting has to add. Section 11(e) of the Charter guarantees the right not to be denied reasonable bail without just cause. The Supreme Court, in decisions like R v Antic and R v Zora, had spent years pushing the system toward restraint, toward releasing accused people on the least onerous conditions necessary, precisely because pre-trial detention jails people who have been convicted of nothing. Most people held in provincial remand are unconvicted, awaiting trial. And the burden of tighter bail does not fall evenly. It falls hardest on the poor, who cannot meet a surety or a cash condition, and on Indigenous accused, who are already held before trial at rates far above their share of the population. A reverse onus does not ask whether a person did it. It asks them to prove they can be trusted, before anyone has proven they did anything at all.

What is established, and what is not

Established: the law passed, the provisions are real, the political trigger was a specific killing and a specific bail release. Contested and unconfirmed: whether C-48 actually makes the public safer. The data on that is thin and slow, and reasonable people read it differently. What can be said is that a law sold on a single, terrible case now governs the bail of thousands of ordinary accused who will never make a headline. That is the part the catch-and-release slogan leaves out. The same instinct to reach for emergency powers in response to a crisis, weighed in our piece on the first time Canada ever used the Emergencies Act, runs underneath bail reform too. For what a bail hearing is actually deciding, our guide on what a bail hearing decides and your rights at it lays it out.

The verdict

A death of a young officer is a real harm, and a public that demands its courts take dangerous people seriously is not wrong to. But the measure of a bail law is not how it reads after the worst case. It is how it works on the ordinary Tuesday, against the ordinary accused who is poor, or addicted, or Indigenous, or simply unlucky, and who is, until a trial says otherwise, innocent. C-48 shifted the burden onto that person. Whether the country is safer for it is unproven. That the principle of bail moved is not.

This essay draws on the public record: the December 27, 2022 killing of Ontario Provincial Police Constable Greg Pierzchala near Hagersville, Ontario, and the documented fact that one of the men charged with first-degree murder in his death had previously been released on bail in a separate matter involving assault and firearms charges (charges that were allegations subject to the presumption of innocence); the January 14, 2023 letter from all premiers and territorial leaders, originating in the Ontario premier's office, demanding bail reform; and Bill C-48, An Act to amend the Criminal Code (bail reform), which received Royal Assent on December 5, 2023, expanding reverse-onus provisions for certain serious violent, firearms, and intimate-partner-violence offences and directing courts to consider community safety. The constitutional context references section 11(e) of the Charter and the Supreme Court decisions R v Antic and R v Zora. Written with deliberate factual care.
