An Air Canada Embraer ERJ-190, registration C-FHJT performing flight AC-207 from Calgary,AB to Vancouver,BC (Canada ) with 101 people on board, was climbing out of Calgary when an odour was observed on board of the aircraft, which dissipated quickly however. The flight was continued. During the descent towards Vancouver the same odour occurred again prompting the crew to declare PAN PAN PAN. The aircraft landed safely on Vancouver's runway 26R about 6 minutes later.

The Canadian TSB reported maintenance could not identify any fault.
