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 30 Mar '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.Official observations from Environment and Climate Change Canada at Toronto Pearson International Airport confirm the highest temperature on March 30, 2026, reached 21°C between 15:00 and 18:00 EDT under partly cloudy skies and westerly winds gusting to 40 km/h, well exceeding the 15°C threshold. This outcome topped pre-event forecasts projecting 16–17°C amid a broader warm March pattern, including records like 17.6°C on March 7 and 26°C on March 1, driven by persistent high-pressure ridging. Trader consensus at 100% implied probability reflects these verified hourly measurements, with resolution pending final daily summary; only an improbable data correction from sensor error could challenge it, given consistent afternoon peaks.
