TORONTO -- A Canadian class-action lawsuit has been filed on behalf of people who have allegedly been short-changed by TD Bank coin-counting machines over a three-year period.

The suit alleges that the bank had learned of numerous accuracy problems with its coin-counting machines in the United States, but still proceeded with a national rollout of the machines across Canada in January 2013.

The plaintiff in the case is a Kitchener woman named Lisa Ram, who says she counted and sorted her coins before she deposited them in a TD Bank coin-counting machine in the city.

Ram says she had a total of $854.25, but was not credited for $159.50 after depositing the coins.

She alleges that she complained to TD Bank, but they failed to remedy the situation.

The allegations have not been proven in court.

A spokeswoman for TD Bank declined a request for comment, saying in an email that the bank could not comment on the pending litigation.

A statement of claim filed against the bank in Ontario by the Toronto law firm Sotos LLP says that the Canadian machines were retired shortly after they were retired in the United States in May 2016.

The suit was filed as a class action on behalf of everyone who used TD Bank's coin-changing machines in Canada between January 1, 2013 and May 25, 2016.

In order to proceed as a class action, the Canadian suit requires certification from the Ontario Superior Court.

Similar claims have been filed against the bank in the United States on behalf of customers who used the U.S. machines.
