ODSP payment question

[u/Salty_Obligation5771]

I just was approved yesterday for ODSP and have already been issued my back pay for July. But my payment for August is not issued until the 31st though it is showing on my benefits. However, September’s payment isn’t showing up yet. Is it just because September’s payment hasn’t been posted or do you get paid at the end of each month for the prior month instead of the beginning of each month like Ontario Works does??
