Recent forecast guidance from Environment Canada and ensemble models shows Toronto on track for a seasonal warm spell, with southerly flow advecting milder air and ample May sunshine supporting daily highs near 28–29°C. This places the market’s top probabilities on 28°C and 29°C, while 30°C remains plausible if boundary-layer mixing and afternoon insolation peak as projected. Key variables include cloud cover timing and any late-day shower development, which could shave 1–2°C off the maximum; historical May extremes rarely exceed 30°C without strong high-pressure persistence. Updated model runs later today and hourly observations from Toronto Pearson will refine the outlook ahead of market resolution.
