See "Appendix B: Provincial/territorial estimates of physician administrative burden and full-time equivalent gain" on page 37.

For BC specifically, there was this recent article:
Family doctors in B.C. are calling on the province to cut digital red tape, saying outdated systems and unnecessary paperwork are slowing patient care and increasing wait times.
It comes as a new national study shows doctors across the province are spending three million hours per year handling administrative work.
The latest report, released by the Canadian Federation of Independent Business and the Canadian Medical Association, released as part of the Red Tape Awareness Week, found that doctors in B.C. spend nearly 10 hours a week on administrative work.
It estimates that eliminating unnecessary paperwork in B.C. could free up an equivalent of more than 1,400 full-time doctors.
