CRA website: "How much you can expect to receive

The maximum basic amount is:$1,395 for single individuals
The amount is gradually reduced if your adjusted net income is more than $22,944. No basic amount is paid if your adjusted net income is more than $32,244."
The amount you receive from Canada Workers Benefit (CWB) will decrease the higher your adjusted net income is over $22,944. If your adjusted net income is over $32,244, you would receive $0 from the CWB. This means that as your income is higher than $22,944, you will receive less from the CWB.
You can use the calculation sheets on the Canada Revenue Agency's website to find the estimated amount you would receive from the CWB. You can find the Calculation sheets here: Calculation sheets for the Canada workers benefit advance payments.
