ReNew Canada confirms the TTC line reached "substantial completion on December 5, 2025," with the official opening marked 9 February 2026 and service beginning 8 February 2026 - matching the pin's stored date.
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.
