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 2 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source. 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.
Official forecasts from Environment Canada and supporting models project a daily maximum of 28–29 °C for Toronto on September 2, with a 30 % chance of showers and thunderstorms that will increase cloud cover and limit solar heating. High humidity and southerly flow are expected to keep the boundary layer moist, reducing the potential for stronger surface warming while steering patterns favor only modest advection of warmer air. These conditions explain the tight clustering of market-implied probabilities around 28–30 °C, as traders weigh the narrow range of outcomes between partial clearing that could reach 30 °C and persistent cloud/precipitation that may cap the high at 28 °C or below. Historical September averages near 24 °C provide context for the above-normal readings currently priced in.
