This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 7 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent official forecasts from Environment Canada and ensemble model guidance position Toronto's September 7 high near 23–24 °C under mostly sunny conditions with light southerly flow, aligning closely with the 1991–2020 climatological average of 23.7 °C. This consensus underpins the market's concentration of implied probability on 24 °C and 25 °C outcomes. Stable high pressure and minimal cloud cover limit upside potential for 26 °C or higher, while cooler boundary-layer mixing keeps lower tails subdued. Traders are weighting the latest deterministic and probabilistic runs, which show low spread and little risk of significant model shifts before resolution.
