In Ontario, can you ask a judge to reconsider a decision if you believe the judge made an obvious error?
Legacy Legal Services can help Ontario litigants understand when a motion to reconsider may be available, since court decisions are generally final and reconsideration is rare and usually requires unusual and rare circumstances, such as a clear or obvious error that all parties agree on, not a contested issue, and courts focus on the integrity of the process and the interests of justice (for example, see 671122 Ontario Ltd. v. Sagaz Industries Canada Inc., 2001 SCC 59, para. 61 and Gupta v. Lindal Cedar Homes Ltd., 2020 ONSC 7524, paras. 6-9) If you want to explore options before the deadline and discuss whether reconsideration versus appeal is the right path, call (226) 246-3825 for a practical next-step review with a paralegal at Legacy Legal Services.

If a Judge Commits a Mistake Within a Court Decision Is It Proper to Ask the Judge to Reconsider?
Generally, When a Judicial Decision Is Rendered the Matter Is Considered Final and May Be Corrected Only Upon An Appeal to a Higher Court. Only In Rare Circumstances, Such As When the Error Is Obvious and All Parties Involved Agree to a Reconsideration,...

Understanding When It May Be Appropriate to Ask a Judge to Reconsider a Court Decision
The process of law, including the making of a court decision, seeks to bring finality to issues in dispute. Accordingly, once a case is decided the law expects that all involved will respect the decision, including any mistakes within the decision, unless taken by Appeal to a higher court. As such, it is very rare that a Judge will reconsider a decision.
The Law
Although a court, generally, is empowered inherently to control its process, and is therefore empowered to review a rendered decision, whether a court should actually review a decision is highly questionable and is likely to occur only when all parties agree that a decision contained obvious errors and is in need of reconsideration. This view was well explained in Gupta v. Lindal Cedar Homes Ltd., 2020 ONSC 7524 where it was specifically stated:
[6] The court has an inherent jurisdiction to adjust a litigation result after judgment in some circumstances, other than through proper appellate review or as contemplated by r. 59.06. However, this should occur only in “unusual and rare circumstances where the interests of justice compel such a result”: Susin v. Chapman, [2004] O.J. No. 2935 (C.A.), at para. 10. Finality in litigation is to be encouraged and fostered. The discretion to re-open a matter should be resorted to “sparingly and with the greatest care”: 671122 Ontario Ltd. v. Sagaz Industries Canada Inc., 2001 SCC 59 (CanLII), [2001] 2 S.C.R. 983, at para. 61.
[7] In Schmuck v. Reynolds-Schmuck (2000), 2000 CanLII 22323 (ON SC), 46 O.R. (3d) 702 (S.C.J.) at para. 25, Himel, J. emphasized the limited circumstances in which a reconsideration should occur, stating: “It is my view that a party who wishes a reconsideration would have to establish that the integrity of the litigation process is at risk unless it occurs, or that there is some principle of justice at stake that overrides the value of finality in litigation, or that some miscarriage of justice would occur if such a reconsideration did not take place.”
[8] In Gore Mutual Insurance Co. v. 1443249 Ontario Ltd., (2004) 2004 CanLII 27736 (ON SC), 70 O.R. (3d) 404 (“Gore”), at paras. 7-8, Karakatsanis, J. (as she then was) was prepared to re-open her decision in a situation where it was “obvious an error was made by all counsel and by the court.” It was a “case of a clear error.” It was “obvious” that the statutory provision now raised would have changed her determination and all counsel conceded that the provision previously relied upon had no application to the case. Karakatsanis, J. concluded at para. 8 that the “interests of justice are not served by requiring an appeal on a clear error of law that followed inaccurate and incomplete legal submissions of counsel.”
[9] In Scott, Pichelli & Easter Ltd. et al. v. Dupont Developments Ltd. et al., 2019 ONSC 6789, Sossin, J. (as he then was) noted at para. 13 that a “motion for reconsideration is more likely to be successful where the parties agree that an error has occurred, and less likely to be successful where the subject matter of the alleged error remains contested by the parties.”
As stated within the Gupta case, generally, a judicial reconsideration is unlikely unless all parties involved agree that a judicial error occurred and that a reconsideration is a just means to seek a correction of the error.
Summary Comment
When a court renders a judicial decision the issues in dispute are, generally, deemed final unless reversed or corrected via the appeal process; however, where the parties involved agree that the decision contains an obvious error and that a request to reconsider is a just way to remedy the error, although very rare, it is possible that a court will reconsider.
NOTE: A significant quantity of online searches featuring “lawyers near me” or “best lawyer in” typically indicate a desire for prompt and proficient legal assistance instead of a specific job title. In Ontario, “licensed paralegals” operate under the same Law Society that governs lawyers and have the authority to represent clients in specified litigation areas. Advocacy, legal analysis, and procedural expertise are fundamental to this function. Legacy Legal Services provides legal representation within its licensed scope, focusing on strategic placement, evidentiary organisation, and compelling advocacy directed at achieving swift and favourable resolutions for clients.
