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 6 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 and Climate Change Canada indicate a mainly cloudy September 6 for Toronto with a daytime high near 24°C and humidex values approaching 29 due to elevated moisture, while several numerical models project 20–21°C under northeast flow and increased cloud cover. This range aligns with the late-summer climatological average high of 23.8°C and explains why trader-implied probabilities concentrate on 22–24°C outcomes. Limited model spread and the absence of strong warm-air advection or clear-sky heating keep probabilities for 25°C or higher below 3 percent, with resolution hinging on the final observed maximum from Environment Canada stations.
