@MAOSPE@AirCanada I had the same issue. Mine is from Heathrow To London Aug 17th at 5:40. It wasn't letting me check in earlier, but now it is allowing me to check-in. Still not sure if the flight is a go or not!
Did you receive an email / notice from AC yet?
@AirCanada@AirCanada I sent you a DM two days ago. I'm stuck abroad and have a flight on Sunday and I'm unable to get a hold of anyone. Can you reply ?
