Official forecasts from Environment Canada project a daytime high of 21°C in Toronto under a mix of sun and cloud with a morning shower chance and strengthening northerly winds, aligning with the tight market split favoring 20–21°C outcomes. Multiple global models show peaks clustered between 19–21°C due to variable cloud cover reducing solar heating and dry air advection limiting afternoon warmth. Historical September climatology places typical highs near 20–22°C, with urban heat island effects at Pearson Airport potentially nudging the official reading. Traders appear focused on real-time observational updates and any late-day model revisions that could shift the exact maximum before 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 20 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 forecasts from Environment Canada project a daytime high of 21°C in Toronto under a mix of sun and cloud with a morning shower chance and strengthening northerly winds, aligning with the tight market split favoring 20–21°C outcomes.
