I have mycobacterium abscessus subspecies abscessus, so not MAC. Mine is also the hardest to treat and it is macrolide resistant, so no azithromycin or clarithromycin. The Canadian healthcare system works differently from down there. It takes jumping through bureaucratic hoops to get out-of-province care. I am hoping to talk to a fellow patient in Toronto tomorrow to see if she has any advice. The top NTM doc in Canada is in Toronto. She treats about 30 cases a year of my species. In a city of many millions. Best of luck to you too. I hope they find a treatment that is effective and doesn't cause you any more misery.
