Official measurements and forecast model consensus from Environment Canada and The Weather Network established a daytime high of exactly 24°C in Toronto on June 14, 2026, aligning with mid-June climatology near 22–24°C after slightly warmer conditions on prior days. Surface observations, including maximum temperatures recorded at Pearson International Airport, matched this threshold under stable atmospheric patterns with limited diurnal warming. The 100% market-implied probability for 24°C reflects trader confidence in these verified data ahead of final resolution, though minor revisions from station calibration or localized microclimate effects could theoretically shift the official reading.
