Very few cases reach a courtroom. If yours does, the single thing that matters most is how you give your evidence, and the discipline is the same one you learned at discovery.
Reviewed August 2026The overwhelming majority of civil claims in Ontario settle. If yours is going to trial, it is because something genuinely could not be agreed, and both sides have decided to let a judge or jury resolve it.
It can still settle. Cases resolve in the weeks before trial, on the morning of the first day, and part way through, sometimes after a witness has given evidence that changes how one side sees the case. Do not treat a trial date as the end of negotiation.
Most Ontario civil actions can be tried by a jury if a party serves a jury notice. Simplified procedure actions cannot: those are heard by a judge alone.
Courts of Justice Act, s. 108; Rules of Civil Procedure, rules 47 and 76.02.1.In motor vehicle cases the jury notice is usually served by the defence rather than by the injured person, and the choice between judge and jury is a tactical one your lawyer will have discussed with you long before now. A jury of six decides the facts and the damages; the judge decides the law and instructs them.
One practical difference matters to you as a witness. With a jury you are speaking to six people who know nothing about the case, so plain language and patience matter more.
A civil trial is a public hearing. Anyone can walk in, including members of the public and, in some cases, reporters. Your family can attend, though family members who are giving evidence themselves may be asked to stay out until they have testified.
You will sit with your lawyer. The judge is at the front, the court reporter records everything, and the witness box faces the courtroom. Trials run on court hours with breaks, and there is a great deal of waiting: for rulings, for legal argument the jury cannot hear, and for the schedule to catch up with itself.
Your own lawyer questions you first. The questions are open ended, because a lawyer is not permitted to lead a witness on the substance, and the point is for you to tell the account in your own words.
This is the part clients find easier than they expect. It is also the part that matters most, because it is the first and fullest version of your story the decision maker will hear.
Then the other side's lawyer questions you, and this is the part people dread. It is different from discovery in three ways that are worth understanding in advance.
The discipline is the same as at discovery, and if anything more important. Listen to the whole question. Answer only what was asked. Do not guess. Do not argue with counsel or try to win the exchange, because a witness who spars looks like an advocate rather than a person telling the truth. If a question is unfair, your own lawyer will object; that is their job, not yours.
The other side is entitled to read portions of your examination for discovery into evidence, and to confront you with what you said then if your trial evidence differs.
Rules of Civil Procedure, rule 31.11.Your lawyer will review the transcript with you before trial. Where an answer you gave was wrong, the fix is to have corrected it properly along the way rather than to explain it for the first time from the witness box.
Surveillance, if there is any, may also be played. If it exists, you will have known about it well before trial and will have had the chance to explain the context.
Two of them surprise people.
Witnesses are often excluded from the courtroom until they have given their own evidence, so that one witness does not shape their account around another's. That can include your spouse or family members who are testifying.
And once you are under cross-examination, you will usually be told not to discuss your evidence with your lawyer until you are finished, including over the lunch break and overnight. It feels isolating at exactly the moment you would most like advice. It is normal, it applies to every witness, and your lawyer will explain it before it happens.
You will sit and listen while the other side argues that you are exaggerating, that your injuries are not what you say, or that what happened to you was not anyone's fault. You may hear a doctor who examined you for an hour give an opinion about your life. In a malpractice case you may hear the care that harmed you defended as entirely reasonable.
None of it is personal, and all of it feels personal.
It is adversarial by design, and lawyers become numb to it in a way clients never do. Tell your lawyer in advance if there is particular evidence you will find hard to sit through. Sometimes arrangements can be made. At minimum, nobody should be blindsided.
A trial is the point at which the costs risk becomes real. If the case is lost, or if you do worse than a formal offer the other side made, a costs order can follow. Your lawyer will have gone through those numbers with you at the pre-trial, and should go through them again before the first day.
See legal fees and costs for how that exposure works.
It varies enormously. In a serious injury or malpractice case a plaintiff can be in the box for a day or more across examination in chief, cross-examination and re-examination.
Usually you are entitled to be present throughout, and it is generally better that you are. Discuss it with your lawyer, particularly if there are days where your attendance would serve little purpose.
That is common and nobody thinks less of a witness for it. Ask for a moment or a break. Courts accommodate this routinely.
Say so. "I do not know" and "I do not remember" are proper answers at trial exactly as they were at discovery, and far better than a guess that gets tested.
A jury usually returns a verdict within days of the end of the trial. A judge sitting alone often reserves, meaning the decision is released in writing weeks or months later.
Yes, and cases do, sometimes part way through. A trial date does not close off negotiation.
