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 16 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 Environment Canada forecasts projecting a Toronto daytime high near 21 °C under partly cloudy skies with moderate southerly flow have driven the market’s strong consensus around that exact outcome. Lake Ontario’s moderating influence typically caps spring extremes in mid-May, aligning with climatological averages of 18–20 °C for the date and limiting warm-air advection from the south. Any brief clearing could allow a brief spike toward 22 °C, while increased cloud cover or scattered showers would keep readings capped at or below 21 °C. Final official observations from Pearson International Airport will resolve the market once the daily maximum is confirmed later today.
