**Official forecasts position Toronto's September 20 high near 19–21°C, aligning with the market's top probabilities (20°C at 36.5%, 21°C at 25%, 19°C at 19%).** Environment Canada projects a 19°C high under mostly cloudy skies with a 30% chance of showers and northerly winds, which suppress daytime warming. Some numerical models and private forecasts reach 20–21°C (roughly 68°F) if partial clearing occurs in the afternoon, while historical averages for the date hover around 21°C. Trader sentiment reflects this narrow range and model spread, with low odds on 22°C+ or cooler outcomes indicating limited expected deviation from current guidance ahead of final observations.

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.
