FM-CFS Canada has talked to support groups and physicians across Canada and all report a severe shortage of chronic pain physicians and multi-year waiting lists. We don't charge you to convey this news.
Medical associations can supply names of physicians to you for free.
Unfortunately, the evidence suggests there are a shrinking number of chronic pain specialists, leaving clinical practice for various reasons, leaving thousands of former patients with no one to replace them. In some countries 'certified-as-Expert' patients have been helping ease the shortage. You may find your local support group is your best source of local information.
