The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
A target, per the source: "2031 remains a target opening date," though Metrolinx's own CEO says the line may open later, in the "early 2030s."
The Globe and Mail quotes Metrolinx CEO Michael Lindsay saying construction is "trending towards the early 2030s" rather than the original 2031 target, supporting the pin's dateConfidenceReasoning and its stored 31 December 2031 estimated date as an optimistic bound.[1]
CBC could not be fetched (403 error), but its own headline, "Ontario Line likely won't open until early 2030s", and 1 February 2026 publish date corroborate the same slippage past the pin's stored 31 December 2031 target that the Globe and Mail source independently reports.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
