The location here is Air Canada headquarters the company Gaëtan Dugas worked for.
Gaëtan Dugas (French: [ɡaetɑ̃ dyˈɡa]; February 20, 1953 – March 30, 1984) was a French Canadian who worked for Air Canada as a flight attendant. Dugas became notorious as the alleged patient zero for AIDS, though he is now more accurately regarded as one of many highly sexually active men who spread HIV widely before the disease was identified.
