Official meteorological observations for Toronto on September 9 confirmed a daily maximum of 24°C, establishing the market resolution and driving the near-certain trader consensus. Environment and Climate Change Canada data, cross-verified with regional station reports, showed temperatures peaking at that level under stable high-pressure conditions with minimal diurnal variation. Historical September baselines for the region typically range 20–23°C, making the observed value consistent with recent warm anomalies but below extreme thresholds. With the date now past, no further forecast revisions or model runs can alter the outcome, though minor data adjustments from quality-control processes remain theoretically possible before final certification.

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 9 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.Official meteorological observations for Toronto on September 9 confirmed a daily maximum of 24°C, establishing the market resolution and driving the near-certain trader consensus.
