HALIFAX -- The legendary Queen Mary 2 arrived in the Halifax Harbour just before midnight on Saturday and was spotted by a number of people.

The Halifax Port Authority says the ship pulled into the port to attend to a medical emergency on board, but no further details on the patient were available.

The Queen Mary 2 was making its usual trip between New York and Southampton at the time.

While unscheduled stops are rare, officials say they do happen – especially with hundreds of thousands of passengers on cruise ships at any given time.
