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 1 Apr '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.

"context_description": "Environment Canada’s latest forecast models, including the high-resolution GEM regional model, project a daytime high of 10°C in Toronto today under increasing cloudiness and light northerly winds of 20 km/h, suppressing peak insolation and limiting warming after a cool overnight low near 2°C. This aligns with trader consensus at 98.2% implied probability, backed by consensus across global models like ECMWF and GFS, which show consistent cool air advection from recent frontal passage. Historical early-April averages hover around 8–10°C, reinforcing the positioning. Realistic challenges include unexpected afternoon clearing for extra solar heating or a stalled warm front, potentially pushing toward 11–12°C; monitor hourly observations from Toronto Pearson International Airport through late afternoon for shifts.",
