The virus seems to be common.

Yes, but the story is bizarre:

When the train reached Winnipeg on the afternoon of July 17, Renshaw said the train was boarded by a crew of people wearing black smocks.

"We called them the men in black," she said. The workers walked around the train, spraying and wiping down surfaces.

"They said they were spraying places that people touched," Renshaw said.

Later that evening, Renshaw noticed a letter posted near her sleeper car.

"It said that a communicable disease was aboard the train, and it was also affecting airlines, buses, and other places where people congregate," she said.

Is there any confirmation of this story in any other media report?

On re-reading, I see that I misread the report. I had thought that people were seen spraying surfaces before the outbreak (making the whole thing suspicious), but it seems that, in fact, they were trying to decontaminate the train after the outbreak started.

This probably was just another natural outbreak of Norwalk virus, which isn't uncommon.

Sorry for wasting your time on this story.
