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 12 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 forecast, issued early April 11 for Toronto Pearson International Airport—the market's resolution source—projects a daytime high of 8°C on April 12 under mainly cloudy conditions with periods of rain beginning in the morning and east winds gusting to 40 km/h, anchoring trader sentiment with 25% implied probability on that outcome. Close competition from 7°C (19%) and 9°C (17%) reflects uncertainty in precipitation timing and intensity, where heavier showers or persistent overcast could cap temperatures at 7°C by limiting solar heating, while lighter rain or afternoon breaks might permit 9°C amid mild advection. Today's partly cloudy high of 10°C with northerly gusts sets a cool baseline, consistent with GEM, GFS, and ECMWF ensemble spreads around 7–9°C; watch hourly updates for refinements ahead of resolution.
