A dog in a suburban Toronto neighbourhood ran away from its owners and hopped a train to downtown.

Marley, also known as Marbles, ran away from his owners and got on a GO Transit commuter train at the Rouge Hill station in Toronto’s east end on Saturday.

Owner Kia Andersen said in a Facebook post that the train conductor called and let her mom Dorte Petersen know “the good news is we have your dog, but the bad news is he is headed to Union Station with us.”

Dorte Petersen thought Marley was at home with her until she got a call from someone on the GO Train, letting her know the mischievous dog was on the train to Union Station.

She admits she’s stumped as to how he got out.

“Only Marley knows, I'd love to see that footage,” she said.

Their gate was shut, but somehow the six-year-old border collie-shepherd mix snuck out after her son had left the house.

“He has rode the elevator for the GO Train all summer with me. I had been in a wheelchair so we were using it to access the path on the other side so he was very familiar with that elevator,” Dorte explained.

“I think when he got outside and went looking for me, that’s what brought him to the GO.”

Conductor Eric Petersen, no relation to Dorte, took control of the situation.

“I just thank you so much for being so kind and so lovely to him and to me, because really I was mortified my dog had gotten out,” Andersen said.

GO Transit spokesperson Anne Marie Aikins told Toronto news station CP24 that Marley must have misunderstood a new policy being tested out that allows leashed dogs on board trains outside of rush hour.

“You’re supposed to have your human with you!” she wrote.

“We are still investigating whether Marley tapped his Presto card,” Aikins tweeted. “He needs to come back in for questioning but we won’t be too ruff.”

Happy story of the year: our family dog Marley (aka Marbles) took the GO train to UNION STATION by HIMSELF... Posted by Kia Andersen on Sunday, August 5, 2018
