International dress mystery: English rail service, Montreal department store, Air Canada search for owner

A simple case of lost luggage in England sparked a transatlantic effort to track down the woman who lost it.

Train officials at the Kingston-upon-Hull station in northeastern England were surprised in early March to find a lost bag full of formal dresses that appeared to be from Montreal.

"It was a bit of a step back in amazement, draw in breath moment," said David Bliss, lost property manager at Hull Trains.

"We opened the case to see if we could find any more information and there, behold in front of us, was what we thought was a rather ornate bright white wedding dress."

Bliss told CBC News that while the incident was a common case of passenger luggage mix-up — this one particularly caught his attention.

"We thought 'Oh dear, if someone's going to a wedding we have to do something about this.'"

Montreal department store lends a hand

The baggage mix-up included bags came from Montreal department store Standa, located on Fleury Street East.

With their contact information printed on the bags they were easy to find and got pulled into the search.

Standa's Liboria Gracioppo saw the photos and realized the white dress must belong to a flower girl, not a bride. 

"We posted it on Facebook and the response was crazy,'" she said. "Within a couple of days, we had 11,000 views."

Headed for a happy reunion

The search for the bag's owner eventually made its way to Air Canada. 

The rail company contacted them for help, thinking Air Canada could find the person via their luggage tags.

While the airline couldn't release details about the woman in question, they did confirm that they've been in contact with her about the case.

"We are thrilled to be part of the efforts to reunite one of our customers with a bag she inadvertently left on a train in the United Kingdom after arriving from Canada on one of our flights," said Air Canada spokesperson Isabelle Arthur.

"We are hoping for a happy reunion very soon," wrote Arthur.
