Learn the difference between the evidence needed for police to lay a charge and the much higher standard the Crown must meet to secure a conviction in court.

A common misunderstanding

Many people believe police must have airtight proof before laying a criminal charge. That is not how the system works. The threshold for a charge is lower than the threshold for a conviction, and that difference explains why some cases that sound serious at the beginning become much weaker once disclosure is reviewed.

The charging stage

Police investigate and, where they believe there are reasonable grounds to believe an offence has been committed, a person may be arrested and charged. In practical terms, that means a case can begin even when there are major questions still to be answered. A single witness statement, a complaint, physical evidence, digital communications, or officer observations may be enough to start the process.

The prosecution stage is different

Once a file reaches the prosecution stage, Crown counsel must continue assessing whether there is a reasonable prospect of conviction and whether it is in the public interest to proceed. That is a different and more demanding question than whether there were grounds to lay the charge in the first place.

Why the distinction matters

This distinction matters because being charged does not prove the case is strong. It only means the process has started. By the time disclosure is produced, the defence may identify inconsistencies, missing evidence, credibility concerns, legal breaches, or alternate explanations that substantially change how the case should be viewed.

What kinds of evidence often matter most

The answer depends on the offence. In some cases, the file turns on witness credibility. In others, the decisive issue is video footage, phone records, forensic evidence, or whether the police investigation respected constitutional protections. An experienced defence lawyer looks not just at what evidence exists, but also how it was obtained, preserved, and disclosed.

Can charges be laid on one person’s word?

Sometimes yes. A complaint from one witness can be enough to start a case if police believe there are reasonable grounds. But that does not mean the evidence will ultimately support a conviction. At trial, reliability, motive, contradiction, memory problems, and missing corroboration can become central issues.

Why early defence work is important

The earlier evidence is preserved, the better. Texts, emails, surveillance, timelines, and third-party witnesses can disappear quickly. Waiting too long may make it harder to challenge a version of events that later solidifies in the court record.

Police do not need trial-ready proof to lay a charge. The real legal fight is whether the evidence can withstand scrutiny and satisfy the far higher standard required in court.

Frequently Asked Questions

Do police need enough evidence to convict before laying a charge?

No. Laying a charge and proving guilt at trial are different steps with different thresholds.

What is the difference between a charge and a conviction?

A charge starts the case. A conviction only happens if the Crown proves the offence in court or the accused enters a guilty plea.

Can weak cases still go to court?

Yes. Some cases proceed even though the defence later shows the evidence is unreliable, incomplete, or legally problematic.
