I don’t have the answer you’re looking for, but I’m going to go out on a limb and say that in order to be able to claim insurance, a massage therapist would be required to operate a legitimate practice, operating under licence, and registered through the province. Breaching their ‘code’ would then render them inoperable. I would be surprised if you were able to find what you are looking for. But, it takes all kinds I suppose. Best of luck.
