Official hourly observations from Environment Canada at Toronto Pearson International Airport—the designated station for this market—confirm the highest temperature on April 18 reached exactly 20°C at 2:00 PM EDT, amid partly cloudy skies, northwest winds around 15-20 km/h, and moderating highs after midday. This precise measurement, captured by automated sensors and standard meteorological protocols, underpins the trader consensus implying 100% probability for 20°C, reflecting the skin-in-the-game wisdom of prediction markets on resolved weather outcomes. While final daily summaries undergo routine quality control within 24-48 hours, realistic challenges would require rare instrument recalibration or data anomaly detection shifting the max beyond 20°C, a scenario with negligible historical precedent at this major airport site.

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 18 Apr '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.
