This August 2017 letter from Ontario Health Minister Hoskins mentions: 'doctors/nurse practitioners’s are encouraged to follow clinical practice guidelines developed by specialist bodies.'
It is important to note that one of these specialist bodies is the International and Associated Diseases Society - ILADS - these are evidence based treatment guidelines and currently listed as the only Lyme guidelines on the National Clearinghouse website. https://www.guideline.gov/search?q=lyme
The Federal Lyme Framework also made mention to two different sets of guidelines. The IDSA guidelines and the ILADS guidelines.
Directly from the Federal Lyme Framework: 'There are a small number of front-line health professionals who follow guidelines developed by the International Lyme and Associated Disease Society (ILADS), a multidisciplinary medical society dedicated to the diagnosis and treatment of Lyme and its associated diseases. The treatment recommendations in the ILADS guideline are different from those in the IDSA, particularly with regards to antibiotic use. There remain evidence gaps which can be informed through further research on treatment options. Emerging evidence will be closely monitored and shared with patients, front-line health professionals, and other relevant stakeholders.' https://www.canada.ca/en/public-health/services/publications/diseases-conditions/lyme-disease-canada-federal-framework.html#a5-3
