Current forecast models from Environment and Climate Canada and the Global Forecast System show Toronto’s May 22 high temperature likely falling between 14 °C and 17 °C, with ensemble means centering near 15–16 °C. A slow-moving frontal boundary and variable cloud cover are introducing modest uncertainty in daytime heating rates, while light southerly flow limits strong advection of warmer air. These conditions align with the tightly bunched market prices that assign roughly 84 % combined probability to the four leading outcomes. Updated model runs expected overnight will refine boundary timing and cloud trends ahead of the day’s resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Toronto Pearson Intl Airport Station in degrees Celsius on 22 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Current forecast models from Environment and Climate Canada and the Global Forecast System show Toronto’s May 22 high temperature likely falling between 14 °C and 17 °C, with ensemble means centering near 15–16 °C.
