**Current forecasts from Environment Canada and major models indicate a high of 17°C for Toronto on September 22, 2026, under a mix of sun and cloud with northeasterly winds of 15–25 km/h.** This aligns closely with the market’s leading 17°C outcome at 49.5% implied probability, followed by 18°C at 25.5% and 16°C at 15.5%. A cooler air mass has advected into the region behind recent frontal passage, suppressing temperatures below late-September climatological normals of roughly 20–22°C. Model consensus (including GFS-based guidance) shows limited diurnal warming due to persistent cloud cover and onshore flow from Lake Ontario, with afternoon peaks most likely reaching 16–18°C. Precipitation chances remain low during peak heating hours, reducing the chance of convective cooling or warming deviations. Updated runs through September 20 show little shift in the 17°C peak, supporting the tight clustering of market probabilities around the 16–18°C range as resolution nears.

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.
