A criminal trial in Ontario gives your lawyer and the Crown an opportunity to tell their side of the story to a judge, a jury, or both. The Crown has the burden of proving you guilty beyond reasonable doubt. You do not have the burden to prove yourself innocent. The crown and your criminal trial lawyer will call evidence and cross examine witnesses. In a criminal trial, your lawyer and the Crown will also introduce exhibits and make certain legal arguments before the judge. The judge or the jury will then find you guilty or not guilty.
A criminal lawyer in Ontario courts may also make an argument to suggest that the police have violated your Charter rights or suggest the time that was taken to bring you to trial was too long. Depending on the situation, your criminal trial lawyer will produce countless arguments to negate the credibility of the case against you.
