If you have Employment Income not reported on a T4 slip, and it is under $3,500;

If your occasional earnings exceed $3,500 gross, CRA requires you to report this a "Self-Employed" earnings on a T2125 Statement of Business Activities. You will be required to pay CPP contributions on any net amount (after expenses) that is over the $3,500 threshold.
