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.

CBC's headline, "Ontario Line now costs over 3 times more than initially projected," published August 11, 2026, covers cost overruns rather than confirming an opening date, consistent with the pin's own "estimated" framing based on Wikipedia's[1] cited 2031 target.

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. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
