BayMark Health Services, based in Lewisville, Texas, made its first foray into Canada this month with the acquisition of Canada’s largest chain of methadone clinics, Canadian Addiction Treatment Centers (CATC), a company that includes 72 opioid-treatment clinics, 19 pharmacies and one residential addiction-treatment center, all in Ontario.

This is BayMark’s 10th acquisition since it was formed in 2015, when Webster Capital combined Bay Area Addiction Research and Treatment Inc. (BAART), acquired in June 2015, and MedMark Services, acquired in October 2015 from Capital Resource Partners. That combination created the third-largest methadone provider in the United States.

Previous announced acquisitions included companies in Texas (3) and one apiece in Georgia, Louisiana, Massachusetts, Pennsylvania, Virginia and West Virginia.

Following the Canadian acquisition, BayMark will operate a total of 167 programs; 145 opioid treatment programs, 8 office-based buprenorphine assisted treatment programs, 13 outpatient detoxification facilities and one residential treatment location across 26 states and one province in North America.
