An Air Canada Bombardier C-Series CS-300, registration C-GUPL performing flight AC-466 from Toronto,ON to Ottawa,ON (Canada) with 131 people on board, was climbing out of Toronto's runway 23 when the crew noticed an odour in cockpit and cabin, donned their oxygen masks, stopped the climb at about 10,000 feet and returned to Toronto for a safe landing on runway 24R about 20 minutes after departure.

The Canadian TSB reported maintenance determined the odour was result of de-ice fluid ingestion, not an aircraft fault.
