Methods: Data derived from Canadian Community Health Survey - Mental Health (CCHS-MH) 2012 and Mental Health and Access to Care Survey (MHACS) 2022. Survey-weighted proportions were calculated, and multivariable logistic regression examined associations between LGB status and perceived or unmet needs, adjusting for covariates. Effect modification by age, sex, and race was tested. Results: LGB adults reported higher perceived needs in 2012 (44% vs. 17%) and 2022 (62% vs. 23%) (p < 0.05). Unmet needs remained constant at 50%. Adjusted ORs for perceived need were 2.17 (2012) and 2.88 (2022). Unmet needs were significantly higher in 2012 (OR: 1.53) but not in 2022 (OR: 1.09). No effect modification was observed. Conclusions: Despite progress among heterosexual individuals, unmet needs among LGB adults remain unchanged, highlighting the urgency for tailored, trauma-informed, sexual minority-affirming mental health interventions.enSexual MinoritiesMental Health ServicesHealth Services Needs and DemandHealth Services AccessibilityHealth SurveysCross-Sectional StudiesHealth Status Disparities CanadaNeeds Assessment
