Official Environment Canada forecasts call for a daytime high of 26°C in Toronto on September 16 under mainly cloudy skies that turn to a mix of sun and cloud by midday, with a humidex near 32. Current observations at Pearson Airport show 22°C at mid-morning with light northerly winds and rising pressure, consistent with modest daytime warming. This places the most probable maximum near 25–26°C, aligning with market-implied odds favoring those outcomes over cooler or warmer thresholds. Historical September 16 averages near 22°C underscore the above-normal warmth, while model consensus and limited precipitation risk support limited upside beyond 27°C. Updated observations through the afternoon will refine final resolution.

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 16 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 Environment Canada forecasts call for a daytime high of 26°C in Toronto on September 16 under mainly cloudy skies that turn to a mix of sun and cloud by midday, with a humidex near 32.
