Self Employment or not?

[Camelboy]

Hello Everyone,

Are these jobs considered as self employment or employment for citizenship application? These three jobs do not provide you with T4 slips.

1. Uber driver, regardless the number of hours. According to the Terms of Uber. Uber drivers are considered as INDEPENDENT THIRD PARTY CONTRACTORS WHO ARE NOT EMPLOYED BY UBER OR ANY OF ITS AFFILIATES. It is kind bit confusing because to consider as self employed i have to have a Business number from CRA for tax purposes and collect GST. With Uber, GST is collected by them.
2. Interpreter, working for several Interpretation agencies which requires physical presence, assignment requests are send by these interpretation agencies you either accept or reject based on your availability. Payment is received through Bank deposit
3. Freelance Tutor : assisting high school kids or university students with specific topics and receiving compensation through cash

Also are these type of employments expected to trigger Residence Questionnaires (RQ), or it will be safer to stick with actual employment which produces T4 slips. For Uber and Interpretation I am both dealing with other businesses and they produce paperwork that can proof that I did the work but for tutoring I am on my own, with no paper work to proof it.

Thank you!
