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 13 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&#39;s latest forecast for Toronto Pearson International Airport projects a high of 21°C on April 13, 2026, driven by southwest winds gusting to 50 km/h ushering warmer air masses after overnight temperatures near 5°C and recent cool, showery conditions through April 12. Trader consensus, with market-implied odds tightly split at 34.5% for 21°C and 33.5% for 22°C, reflects uncertainty from persistent cloud cover and a 40% chance of afternoon showers, which could limit solar heating and cap the peak, versus potential clearing allowing a 1°C overrun amid humidex values near 26. Hourly observations through afternoon will clarify the maximum, as short-range model ensembles like GFS and ECMWF show modest spread around this warmer-than-average April baseline of 12°C.
