Hundreds of OC Transpo users started the month of April with new Presto problems.

According to the transit company, there was a delay in the uploading of their monthly passes. This lead to some customers showing an empty balance while trying to tap on, others were simply allowed to ride for free.

“This problem was identified and the fix was made on the same day,” writes David Pepper, OC Transpo’s Manager of Operational Services.

Pepper adds that all of the affected customers were contacted by Presto explaining the situation and delay. They were also given a $10 credit to compensate them for any money spent during the delay.

Representatives of Metrolinx tell CTV the cause of the problem is still under investigation.
