Official Environment and Climate Change Canada observations from Toronto Pearson International Airport—the standard reference station for such markets—confirm the highest temperature on April 21, 2026, reached exactly 11°C during hourly readings amid cloudy conditions and light winds that capped warming. This verified measurement, finalized post-midnight, has driven trader consensus to a 100% implied probability for the 11°C outcome, reflecting the wisdom of crowds in aligning with authoritative data over pre-event forecasts expecting slightly higher peaks around 12–14°C. Realistic challenges are minimal but could include rare data audits revealing sensor errors or disputes over urban heat effects at alternate downtown sites; however, Pearson's records govern resolution, solidifying the positioning absent new evidence.
