An OTB notice is a letter sent to eligible Ontario residents informing them of their status with respect to the Ontario Trillium Benefit. The Ontario Trillium Benefit (OTB) is the combined payment of the Ontario energy and property tax credit, the Northern Ontario energy credit, and the Ontario sales tax credit. The annual OTB entitlement is usually divided by 12, and the payments are issued on the 10th of each month. An OTB notice may contain an update or a request for additional information regarding your participation in the OTB program. There are many reasons why you may have been sent an OTB notice, including simple updates on your OTB application status, notice of general changes to OTB benefit payments, notice that you owe money back to the CRA due to changes in eligibility, or a request for information needed to assess your OTB eligibility. If you receive an OTB notice from the CRA, it is important to read the notice carefully and see if the information is correct and if they require any action from you. You can always contact the CRA directly for assistance if you have any questions or concerns about your OTB notice.
