Trader consensus on the Toronto temperature market has consolidated around a verified maximum of 22°C for October 4, reflecting official surface observations from Environment and Climate Change Canada stations that aligned closely with the final forecast guidance. Early October climatology shows average daily highs near 17–18°C, yet recent atmospheric patterns—including modest southerly flow and limited cloud cover—supported a modest positive anomaly without reaching higher thresholds. With resolution now complete, the market-implied probability near 100% for 22°C rests on the absence of credible alternative readings. Minor revisions in post-processed data or station-specific differences remain theoretically possible but lack supporting evidence from primary monitoring networks.
