I have spoken to the assistant registrar and the NSRP doesn’t have guidelines specific to multidisciplinary practice, however, he did want the opportunity to provide some information for this enquiry. Whenever starting a practice NSRP would recommend that you review the NSRP Standards for Providers of Psychological Service. As well, you could also review the PDF attached for a listing of relevant legislation and other guidance you might see through the lens of operating a clinic:

In a multi-disciplinary clinic, it would be important that the public clearly understands what services they are receiving (whether psychological services versus the other health services that are provided in the multi-disciplinary clinic) and from whom (the qualifications of the provider, e.g., psychologist or one of the other healthcare professionals). This would be consistent with the NSRP position on billing to ensure that billing is transparent about services provided and by whom:

We would also suggest that that document on starting and operating an independent practice might be helpful:
