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 11 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Environment Canada's latest 11:00 AM EDT forecast for Toronto Pearson International Airport projects a high of 10°C on April 11 under mainly sunny skies with northwest winds at 15 km/h, driving trader consensus with 43% implied probability on 10°C narrowly leading 11°C at 42.5%. Hourly guidance shows peak temperatures of 10°C around 4–5 PM, building from the current 5°C at 10 AM amid a cool post-frontal air mass. Differentiating factors include slight model spread among GFS, ECMWF, and GEM ensembles, where fuller solar insolation or lighter winds could boost afternoon heating to 11°C, while lingering clouds or gusts cap it at 10°C; below-climatological norms for mid-April (~12°C average high), real-time observations will resolve this tight uncertainty by evening.
