Environment and Climate Change Canada's forecast, issued April 12 for Toronto Pearson International Airport, projects a daytime high of 20°C on April 14 amid periods of rain and extensive cloud cover, anchoring trader consensus behind "21°C or below" at 68.5% implied probability. This positioning stems from model agreement across the Canadian GEM and global GFS ensembles, which depict a low-pressure system steering moist southerly flow while suppressing solar heating and convective warming—key factors limiting peaks above 21°C. Over the past week, Toronto has warmed above seasonal norms (average April highs near 12°C), but incoming precipitation reinforces the cap. New observational data and forecast updates expected this afternoon could shift odds amid typical short-term model variability.
