Official Environment Canada observations from Toronto Pearson International Airport confirm the highest temperature on March 27, 2026, reached exactly 0°C shortly after midnight, with subsequent readings dropping to -7°C amid gusty northerly winds up to 55 km/h and partly cloudy skies that limited solar heating. This positioning reflects a persistent Arctic air mass following earlier March warm spells—like the 17.6°C record on March 7—now reinforced by a high-pressure ridge steering cold air southward, aligning with pre-event forecasts predicting highs near freezing and consistent with March's climatological average maximum of about 7°C but high variability. Trader consensus at 100% odds embodies this verified data, though rare scenarios like post-preliminary data adjustments or overlooked urban heat microclimates could theoretically challenge resolution.
