This market will resolve to the temperature range that contains the highest temperature recorded at the Toronto Pearson Intl Airport Station in degrees Celsius on 22 May '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Recent official observations from Environment Canada stations, including Toronto Pearson International Airport, recorded a daily maximum of 16°C on May 22, locking in the market’s near-100% implied probability for that outcome. Ensemble forecasts from Environment Canada and global numerical weather prediction models converged tightly on a 14–17°C range, reflecting modest upper-level ridging and limited boundary-layer moisture that suppressed afternoon heating near late-May climatological norms. This strong model consensus, validated by surface data, left minimal uncertainty for resolution. Only an unforecasted localized thermal surge or station microclimate anomaly could have pushed readings outside the 16°C threshold.
