Some Via Rail workers have voted in favour of going on strike if they're unable to reach a new labour agreement with the company.
More than 2,000 on-train and clerical workers voted 94 per cent in favour of strike action if a deal isn't reached by June 27.
A strike would include ticket vendors and maintenance workers.
The employees are represented by the Canadian Auto Workers union.
Further talks are scheduled for the week of June 21.
