R. v. S.L., 2026 ONCJ 61<\/strong><\/p>\n <\/p>\n A Look at R. v. S.L., 2026 ONCJ 61<\/strong><\/em><\/p>\n <\/p>\n Joseph A. Neuberger, Michael P. Bury and Diana Davison, Neuberger & Partners LLP, Criminal Lawyers Toronto<\/p>\n <\/p>\n \n 01<\/strong> \u2022<\/span> BACKGROUND AND PROCEDURAL HISTORY<\/strong>\n<\/p>\n The accused, S.L., stood trial in July 2025 on ten counts arising from alleged sexual assault conduct against his stepdaughter, O.L. The charges encompassed multiple forms of sexual abuse, child-pornography-related offences, and counts of violence and threats. The Crown called two witnesses \u2014 the complainant, O.L., and her mother, C.A. The accused did not call evidence and was convicted on all ten counts. Following the verdict, the matter was adjourned for the preparation of a report under section 21 of the Mental Health Act<\/em>.<\/p>\n Before the scheduled sentencing date, defence counsel received a statement from O.L. that had never been disclosed. The statement had been recorded more than a year before the July 2025 trial \u2014 after charges had already been laid. The investigating officer, DC Norman, elected not to disclose it, characterizing the allegations it contained as different from the charges before the court and indicating no further investigation would be completed. The Crown became aware of the statement in mid-December 2025 and moved promptly to disclose it.<\/p>\n The parties agreed that the trial must be re-opened. They diverged sharply, however, on the appropriate remedy. The Crown proposed recalling witnesses for further cross-examination and requiring the accused to make a fresh election. The defence sought a mistrial.<\/p>\n <\/p>\n \n 02<\/strong> \u2022<\/span> THE UNDISCLOSED STATEMENT: WHY IT MATTERED<\/strong>\n<\/p>\n The newly disclosed statement was wide-ranging in scope. Recorded several months after the initial complaints and after charges had been laid, it substantially expanded upon O.L.’s earlier account and introduced matters that had never previously come before the court. Two portions were of particular significance to the integrity of the verdicts.<\/p>\n O.L. admitted in the statement to having made a false allegation against the accused. She explained that she had lied to her mother in order to provoke a conflict that would cause S.L. to leave the home. She described this as either her “first” or her “only” lie about the accused.<\/p>\n<\/div>\n The statement disclosed “other sexual activity” within the meaning of section 276 of the Criminal Code<\/em>. The account involved alleged sexual abuse by a family member, along with a suggestion that the accused may have been aware of it. Defence indicated it would have sought to admit this evidence to challenge O.L.’s credibility at trial.<\/p>\n<\/div>\n Notably, neither of the investigative reports filed with the court made any reference to O.L.’s admission of a prior false allegation, notwithstanding that those reports purported to summarize the interview and explain the investigator’s conclusions.<\/p>\n <\/p>\n \n 03<\/strong> \u2022<\/span> THE LEGAL FRAMEWORK: MISTRIALS FOLLOWING LATE DISCLOSURE<\/strong>\n<\/p>\n A mistrial is a discretionary remedy of last resort, granted only where no lesser remedy can cure the prejudice to the accused. This principle is well-established in Ontario appellate authority, including R. v. Anderson<\/em>, 2018 ONCA 1002, R. v. Toutissani<\/em>, 2007 ONCA 773, and R. v. Griffith<\/em>, 2013 ONCA 510.<\/p>\n The post-verdict disclosure context was guided by the Court of Appeal’s decision in R. v. Arabia<\/em>, 2008 ONCA 565, which confirmed that the same rigorous standard governing mid-trial applications applies where an accused seeks to re-open a trial after judgment has been rendered. The question is whether the newly surfaced evidence is sufficiently cogent, and whether its late emergence has so compromised the fairness of the proceedings, as to necessitate a complete recommencement.<\/p>\n <\/p>\n \n 04<\/strong> \u2022<\/span> ANALYSIS AND DECISION<\/strong>\n<\/p>\n Although the defence had not seriously challenged O.L.’s credibility at trial \u2014 focusing instead on the reliability of her evidence \u2014 Justice Lalande had nonetheless made positive credibility findings, including describing O.L. as “extremely believable.” The newly disclosed statement had the potential to significantly undercut that assessment, particularly in light of O.L.’s admission of a prior false allegation.<\/p>\n Justice Lalande drew support from three recent decisions confronting analogous circumstances:<\/p>\n The Crown sought to distinguish these authorities on the basis that the new evidence was discrete and extraneous to the factual matrix previously adjudicated. Justice Lalande was not persuaded. Whether the credibility-impacting evidence arose from the same facts or from wholly extraneous matters, the concern identified in Drysdale<\/em> was equally engaged: prior credibility findings, once made, cannot be revisited without generating a structural apprehension of bias.<\/p>\n <\/p>\n “If I were to continue the trial and permit further evidence to be called, short of finding Mr. Drysdale not guilty on all counts \u2026 he, along with reasonably informed members of the public, would always wonder whether my ‘new’ conclusions and reasons were infected by my prior adverse finding of credibility. Whatever result I reached would always be open to question. The only way to address this issue in a manner that is fair to both sides is to start all over again.”<\/em><\/p>\n \u2014 Trotter J., R. v. Drysdale<\/em>, 2011 ONSC 5451, at para. 29, adopted by Lalande J.<\/p>\n<\/blockquote>\n Beyond the apprehension of bias concern, Justice Lalande identified further considerations militating against the lesser remedy.<\/p>\n The Crown witnesses had testified in July 2025. By the date of the application it was late January 2026, with further delay inevitable before any additional evidence could be heard. Justice Lalande cited R. v. Ghanbarbidkorpe<\/em>, [2016] OJ No 6991 (SCJ), in which Justice McDonnell observed that recollection of the manner in which a witness testified is essential to the assessment, and that after a lengthy interval such impressions exist “only in my notes, and in the black and white of my judgment, not in my memory.”<\/p>\n<\/div>\n The defence indicated an intention to bring a section 276 application in respect of the sexual activity disclosed in the new statement. The Supreme Court in R. v. J.J.<\/em>, 2022 SCC 28, and the Court of Appeal in R. v. Ranu<\/em>, 2025 ONCA 663, have signalled in strong terms that such applications should be addressed prior to trial absent compelling circumstances. Hearing the application in the interval between the original evidence and the recalling of witnesses would generate further delay and engage additional unfairness concerns.<\/p>\n<\/div>\n Justice Lalande acknowledged, with evident care, the position of O.L. A mistrial would require her to participate in a new trial and potentially in a section 276 application. The Crown’s proposed remedy would likewise subject her to further testimony. The court nonetheless concluded that a mistrial was the fairest overall remedy, explicitly recognizing that O.L. bears no responsibility for the investigator’s failure to disclose and that the burden now imposed upon her is an unjust consequence of institutional failure.<\/p>\n<\/div>\n <\/p>\n \n 05<\/strong> \u2022<\/span> DISPOSITION<\/strong>\n<\/p>\n <\/p>\n OUTCOME<\/strong> \u00b7 Application to re-open granted on consent \u2014 mistrial declared \u2014 new trial to proceed<\/p>\n<\/div>\n The application record was marked as Exhibit 1 on the voir dire<\/em>, with certain tabs sealed from public access pending prior judicial approval.<\/p>\n <\/p>\n \n 06<\/strong> \u2022<\/span> COMMENTARY AND IMPLICATIONS<\/strong>\n<\/p>\n <\/p>\n \n 07<\/strong> \u2022<\/span> CONCLUSION<\/strong>\n<\/p>\n R. v. S.L.<\/em> is a significant decision on the intersection of disclosure obligations, post-verdict remedies, and the structural limits of judicial impartiality. It confirms that the remedy for late disclosure fundamentally undermining trial fairness is not surgical re-opening but wholesale recommencement. The decision reinforces that the Crown’s disclosure obligations \u2014 and by extension those of investigators acting on behalf of the state \u2014 are not procedural formalities but constitutional conditions of a fair trial. When they are breached, the consequences are severe, and they fall not only on the accused but on complainants, witnesses, and the administration of justice itself.<\/p>\n <\/p>\nCan a Verdict Stand When Key Evidence Was Never Disclosed?<\/h1>\n

2011 ONSC 5451<\/td>\nEvidence emerging at sentencing supported the accused’s testimony on a credibility-related issue.

2025 ONSC 6371<\/td>\nA mistrial was declared during the defence case after a phone extraction raised credibility issues on facts central to the litigation, including the complainant’s stated age at the time of the alleged offence.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n \n

\n 1<\/strong><\/td>\n The disclosure obligation is unequivocal.<\/strong> The Crown’s obligation under R. v. Stinchcombe<\/em>, [1991] 3 SCR 326, is not subject to the unilateral judgment of investigators as to what is or is not relevant to the charges before the court. The statement in this case contained an admission by the complainant of a prior false allegation \u2014 plainly material to the defence \u2014 yet the investigator withheld it on the basis that the allegations it contained were “different” from those charged. That reasoning does not withstand scrutiny.<\/td>\n<\/tr>\n \n 2<\/strong><\/td>\n Investigator conduct is squarely implicated.<\/strong> The failure in this case rested with DC Norman, who made a unilateral determination that the statement was not relevant and accordingly did not disclose it. The identification of potentially relevant material for disclosure is a prosecutorial function, not an investigative one. Investigators who make these determinations independently \u2014 and incorrectly \u2014 risk triggering precisely the kind of catastrophic remedial outcome seen here.<\/td>\n<\/tr>\n \n 3<\/strong><\/td>\n The credibility apprehension problem is structural.<\/strong> The reasoning in Drysdale<\/em>, Aguilar-Lopez<\/em>, and Maharaj<\/em>, now endorsed in S.L.<\/em>, establishes a clear principle: once a trial judge has made positive credibility findings in respect of a witness, and material emerges post-verdict that has the potential to undermine those findings, the judge cannot fairly revisit them. The structural apprehension of bias that arises in such circumstances is not curable by anything short of a fresh trial before a different trier of fact.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
