Do I have to use Form 72-503F if I’m filing under OSC Rule 72-503?

No. If you are an issuer other than an investment fund relying on a prospectus exemption in OSC Rule 72-503, OSC Staff would not object to you filing a Form 45-106F1 instead of a Form 72-503F provided (a) you complete Form 45-106F1 within the time frame required for the filing of that form, (b) the Form 45-106F1 includes the information that would otherwise be required in Form 72-503F, (c) Form 45-106F1 is completed in its entirety (including the schedules), and (d) you pay the prescribed filing fee for Form 45-106F1.
