Recent Environment Canada guidance and converging model runs point to a high of 21–22 °C for Toronto on September 18 under mostly sunny skies and northerly flow. High pressure near 1023–1024 hPa and dew points in the low teens support modest daytime warming without significant moisture or instability, keeping the temperature close to the late-summer climatological average. Trader positioning favors 21 °C (50.5 % implied) over 22 °C (31 %) because several guidance suites, including GFS-derived products, cluster near 20.5–21.5 °C once boundary-layer mixing and cloud cover are accounted for. Any late upward revision in the official forecast or a shift to lighter winds could quickly elevate the 22 °C contract, while persistent northeasterly flow would reinforce the current 21 °C lead.

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 18 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.Recent Environment Canada guidance and converging model runs point to a high of 21–22 °C for Toronto on September 18 under mostly sunny skies and northerly flow.
