CRA Tax Data Delivery service - Certain slips tripled as a result of download

Dear Cantax client:

Because of a technical problem, the CRA's Tax Data Delivery service is currently not available. We are working jointly with the CRA to solve this problem as quickly as possible. For that reason, we suggest that you try using the service again later.

Also note that a problem relating to the CRA systems occurred on March 3, 2015. If you downloaded data on that date, certain slips might have been downloaded three times into the TDD form. We have determined that this problem occurred for T4 and T4A slips. However, make sure that this problem does not affect other slips.

Thank you for trusting our software program.
