Lacasse was named to the Canadian senate at the age of 37 and died in office 25 years later. In 1944, Lacasse was reproved in the rabies fatality of a 11-year-old boy.
Appointed medical health officer and acting as physician to the family, Lacasse did not administer the Pasteur treatment when the boy was bitten by a rabid dog.
