Massage Therapist GST Question - Invoicing, collecting GST and remitting to the CRA.?

[ZenYouDoIt]

I'm a Massage Therapist and I work at a clinic where I invoice my services hourly there. I'm not sure if I'm doing things right but the situation is like this. I treat many clients and the majority are MVA (Motor Vehicle Accident) clients. The clinic bills the insurance for MVA treatment and don't collect GST on their treatment plan like massage and chiropractic treatment. I do get people who are not MVA and just want Massage Therapy (private clients). The clinic collects the fees and GST for private clients. I keep track of the private clients include the GST to collect for each one on my invoice and bill to the clinic.

Do I just remit the GST to the CRA that I collect from the private clients only?

Or does my total hourly on my invoice is subject to 5% GST to remit to the CRA?
