**Forecast consensus from Environment Canada and numerical models positions a daytime high near 16°C as the leading outcome for Toronto on October 5.** A northwest cold front has advected cooler, drier air behind earlier showers, with clear skies, gusty winds to 40–60 km/h, and minimal cloud cover limiting daytime heating. This aligns with climatological norms for early October, when average highs decline from ~18°C to the mid-teens amid strengthening westerlies and shorter daylight. Recent model runs show tight agreement around 15–17°C, with the 16°C bin capturing the highest implied probability as traders weigh official observations against minor forecast spread. Resolution will hinge on the maximum temperature recorded at primary stations before midnight local time.
