Current forecasts from Environment Canada indicate a daytime high near 23°C on September 6 with clearing skies overnight, supporting a minimum around 12°C amid light winds and moderate humidity. This positions the outcome near the 15°C or 10°C-or-below brackets, where market-implied odds cluster tightly due to small differences in model guidance on radiative cooling rates and Lake Ontario moderation. Historical September averages place typical lows near 15.5°C, but recent model runs show modest spread from urban heat retention versus clear-sky heat loss. Final Environment Canada updates and observational data before midnight will refine the exact threshold.

This market will resolve to the temperature range that contains the lowest 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 lowest 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.Current forecasts from Environment Canada indicate a daytime high near 23°C on September 6 with clearing skies overnight, supporting a minimum around 12°C amid light winds and moderate humidity.
