Unless you have specifically entered into an agreement to pay EI on self employed earnings, you aren't required to do so.  As to CPP, you take the net business income, subtract $3500, and multiply that amount by 9.9%.  Half of that is recorded at line 222 of the T1 as a deduction, the other half is shown at line 310 on the Schedule 1 as a credit, and the total amount is shown as a payable at line 421 of the T1.
