Lyme disease 'definitely spreading' in Canada, expert warns
Once found only in Ontario, Lyme-carrying ticks are now found in almost all the provinces. As they continue to spread, medical professionals are increasingly concerned about Canadians contracting the disease. "The distribution has changed," infectious disease specialist Dr. Neil Rau told CTV's Canada AM on Monday. Rau said the risk of contracting Lyme disease used to be limited to Point Pelee and Fort Erie, near the U.S. border in southern Ontario.
