- June 19, 2026
- Area of law
- Employment Law
- Key issue
- Whether an Ontario court can defer costs and trial assignment decisions after a summary judgment motion is discontinued mid-stream due to late document production in an employment dispute.
- Outcome
- The court deferred the costs of the discontinued motion to the trial judge, declined to designate the motion judge as trial judge, retained her as case management judge, and directed that further examinations for discovery be completed before any additional motions proceed.
- Why it matters
- Employees in complex wrongful dismissal cases need to understand that a discontinued summary judgment motion does not end their case and that late document production by the other side can trigger important procedural protections, including the right to further discoveries before any new motion is heard.
Legal principle
The rule from this case
When a summary judgment motion is discontinued in Ontario — particularly because significant new documents were produced late — the court does not automatically assign costs against either party. Instead, the costs question is best left to the trial judge, who will have the full evidentiary record needed to assess why documents were produced late and how that affected the fairness of the proceeding. A judge who managed a summary judgment motion that never reached a complete record is not automatically seized as the trial judge. The court may retain that judge in a case management role to preserve continuity while leaving the trial assignment open, and may direct that outstanding discoveries must be completed before any further motions are brought, ensuring the record is adequate before the next procedural step.
Important limits
What this does not mean
This decision does not mean that costs are never awarded against a party whose late document production causes a motion to collapse — it means only that, in these circumstances, the trial judge is better positioned to make that call once the full picture is known. Parties should not assume that producing documents late will automatically shield them from a costs order. The case also does not establish that a motion judge is always ineligible to serve as trial judge after a summary judgment motion is discontinued, nor that case management is available in every Ontario employment dispute as of right. The court's directions here were specific to the procedural posture of this file, including its multiple defendants, large document volume, and mid-litigation amendment requests, and should not be read as a general rule applicable to all wrongful dismissal proceedings.
What happens when a summary judgment motion is abandoned in Ontario?
When a summary judgment motion is discontinued — meaning one side pulls it before the judge decides — the case does not simply end. The court must sort out what comes next: who pays the costs of the failed motion, whether the same judge stays involved, and how the parties get ready for trial. A recent Ontario Superior Court of Justice decision, Wenbin (Vincent) Ke v. Sam Cooper et al., 2026 ONSC 3454 (CanLII), walked through exactly these questions after a summary judgment motion in an employment dispute was halted following new document production.
What is a summary judgment motion and why do employment cases use them?
A summary judgment motion asks a judge to decide the case — or part of it — without a full trial. It is faster and cheaper than trial, which is why it is popular in employment disputes such as wrongful dismissal claims. The moving party argues that there is no genuine issue requiring a trial: the facts are clear enough that a judge can rule right now.
Summary judgment is not always the right tool, though. If significant new evidence surfaces during the process — for example, a large batch of documents that were not previously disclosed — the factual picture can shift enough that a judge cannot fairly resolve the matter on the existing record. That is essentially what happened here, and the motion was pulled before a decision was reached.
Who pays the costs of a discontinued summary judgment motion in Ontario?
Costs do not automatically follow the losing party when a motion is discontinued rather than decided. The court in this case concluded that the trial judge is best placed to decide who should bear the costs of the abandoned motion. Because newly produced documents changed the landscape significantly, it would be unfair to assess blame — and costs — before the full picture emerges at trial.
This is an important practical point. In Ontario employment litigation, costs can be substantial. A summary judgment motion involves preparation, affidavits, factums, and hearing time. If a motion is discontinued because one side produced documents late, the question of whether that party should pay the wasted costs is often best answered by the judge who hears all the evidence and understands the full context.
Can the judge who managed the summary judgment motion also be the trial judge?
Not necessarily — and not automatically. The court here distinguished the situation from cases where a motion judge hears a full record and then declines to grant summary judgment. In that scenario, some courts have found it efficient for the same judge to proceed directly to trial.
Here, the motion never reached a complete record. The judge declined to seize herself as the trial judge at this stage, finding it premature. She will, however, remain involved as the case management judge, which keeps continuity in managing the file while leaving the trial assignment open.
What is case management and how does it protect employees in complex disputes?
Case management is a court process where a single judge oversees a file from early stages through to trial, issuing directions and keeping things on track. It is especially valuable in employment cases that involve multiple defendants, large volumes of documents, or procedural disputes.
In this matter, the case management judge directed that further examinations for discovery must be completed before any additional motions proceed. Given the volume of new documents produced, counsel needed the opportunity to question the defendants about those materials before anyone could bring another motion. This kind of structured sequencing prevents parties from rushing ahead before the record is complete — a protection that benefits both sides but is particularly important for plaintiffs who may be outgunned in resources.
Can a plaintiff amend their claim or add a jury notice partway through litigation?
Yes, but it requires a formal motion, and the other side has the right to object. In this case, the employee sought to amend the statement of claim and to file a jury notice. The defendants opposed, arguing the changes were unnecessary and tactical.
The court declined to deal with those requests informally. Instead, it directed that they be brought on a proper motion after the further examinations are complete. This is consistent with how Ontario courts generally handle mid-litigation amendments: the request must be justified, the other side must have a fair chance to respond, and the timing must make sense in the overall flow of the case. Our Ontario employment lawyers regularly advise clients on when and how to bring or oppose amendment motions.
Practical takeaways for employees in complex Ontario employment litigation
- Late document production can reshape your case. If the other side produces a large volume of new documents, you may have the right to conduct further examinations before any motion proceeds — insist on it.
- Costs of a failed motion are not automatically yours to bear. When a motion is discontinued because of changed circumstances, courts may defer the costs question to trial, where the full story can be assessed.
- Case management is your friend. In disputes involving multiple defendants or complicated facts, ask whether your matter should be case managed. A single judge overseeing the file can prevent procedural ambushes.
- Jury notices and claim amendments have their own process. Do not expect a court to deal with these requests informally — plan for a formal motion and give yourself enough time after discoveries are complete.
- Sequencing matters. Courts will generally require that discoveries are finished before further motions proceed. Rushing ahead can backfire and waste costs.

FAQ
Frequently asked questions
Discontinuance means the party who brought the motion withdraws it before the judge makes a decision. The case continues toward trial, and the court must then deal with outstanding procedural questions such as costs and next steps.
Yes. A discontinued or unsuccessful summary judgment motion does not end your case. The matter proceeds to trial in the ordinary course, often with directions from the court about what steps must be completed first.
Ontario courts often leave that decision to the trial judge, who is better positioned to assess why the documents were produced late and how that affected the overall fairness of the proceeding.
