Ontario Family Court Appeal and Costs: What Grandparents Should Know

What Happens After the Judge Decides

When an Ontario family court judge issues a final order on a grandparent's decision-making responsibility application, that order is binding and enforceable. But what if the decision goes against you — or against the parent — and one side believes the judge made a legal error?

Ontario's appeal routes differ depending on which court made the original decision, and the costs of an appeal can exceed the costs of the original proceeding. Understanding both before you file helps you decide whether an appeal is a realistic option.

Appeal Routes by Court

From the Ontario Court of Justice (OCJ): Under section 73(1)(a) of the Children's Law Reform Act (CLRA), an appeal from an OCJ order under Part III of the Act goes to the Superior Court of Justice (SCJ). The route and grounds depend on the order and the applicable legislation; do not assume every appeal is limited to a question of law.

From the Superior Court of Justice (SCJ) or Family Court Branch: Under section 73(1)(b) of the CLRA, an appeal from a Family Court order under Part III goes to the Divisional Court. An appeal from an order of the SCJ outside the Family Court branch goes to the proper appellate court under section 73(1)(c) and the Courts of Justice Act. Some CLRA jurisdiction and extra-provincial orders go directly to the Court of Appeal under section 73(2).

Important distinction: An appeal is not a new trial. The appellate court does not re-hear witnesses or re-weigh evidence. It reviews the trial judge's decision to determine whether a legal error was made, whether the judge misapplied the best interests test under section 24(3) of the CLRA, or whether the factual findings were unreasonable on the evidence.

Grounds for Appeal

Not every unfavourable decision is appealable. Common grounds that appellate courts recognize:

• Error of law — the judge applied the wrong legal test, misinterpreted a statutory provision, or failed to consider a mandatory factor under section 24(3)
• Procedural unfairness — a party was denied the opportunity to present their case, evidence was improperly excluded or admitted, or the judge showed bias
• Palpable and overriding error of fact — the judge's factual findings are clearly wrong based on the evidence in the record (a high bar to meet)
• Unreasonable exercise of discretion — the judge's decision falls outside the range of reasonable outcomes given the evidence

Disagreeing with the judge's weighing of best interests factors is usually not enough. Appellate courts give significant deference to trial judges who saw the witnesses, assessed credibility, and weighed the evidence firsthand.

Timelines

Appeal deadlines are strict, and service, filing, and leave deadlines can differ by route:

• In many appeals, the notice must be served within 30 days of the order. Some routes require the notice to be filed within a further 10 days after service.
• If a Divisional Court leave motion is required, the notice of motion must generally be served within 15 days and filed within 5 days after service. Different rules may apply in particular proceedings.
• Get legal advice promptly and check the current rules for the court that will hear the appeal. Missing a deadline can affect your right to appeal.

Costs in Ontario Family Court

Ontario family courts have broad discretion to award costs — ordering one party to pay some or all of the other party's legal expenses. Costs awards are governed by Rule 24 of the Family Law Rules.

How costs work:

• The court considers success on the main issues, the parties' conduct, and any offers to settle
• A party who makes a reasonable settlement offer that the other side rejects, and then does better at trial than the offer, is in a strong position for a costs award
• Self-represented litigants can receive costs for disbursements (filing fees, process server fees, photocopying) but generally not for the time they spent on the case
• Costs awards in family court are typically modest compared to civil litigation, but they can still range from a few hundred to several thousand dollars

For grandparents on fixed incomes: The risk of a costs award against you is a factor in deciding whether to pursue litigation or seek a consent resolution. If you lose at trial and the other side was reasonable in their proposals, the court may order you to pay a portion of their costs.

The Real Cost of a Grandparent's Application

The total cost depends heavily on whether the case settles or goes to trial:

Self-representing through the case conferences and even trial is common for grandparents who cannot afford representation. The out-of-pocket costs for a self-represented applicant who files in the OCJ can be under $200 total if the case settles at the settlement conference.

When an Appeal Is Worth It

Consider an appeal when:

• The judge made a clear legal error (misapplied the CLRA, failed to consider mandatory factors)
• The outcome puts the child at genuine risk
• You have legal advice confirming the grounds are strong
• You can afford the cost or qualify for legal aid

Think carefully about an appeal when:

• You simply disagree with how the judge weighed the evidence
• The child's circumstances have changed since the trial (a variation application may be more appropriate than an appeal)
• The costs would create financial hardship without a strong likelihood of success

Managing Costs From the Start

The most effective way to manage costs is to resolve the case early — ideally at mediation or the settlement conference rather than at trial. The Ontario decision-making order toolkit helps self-representing grandparents and relatives organize their filing package efficiently, reducing the procedural errors that extend timelines and increase costs.
