The Public Health Agency of Canada said there were 1,394 cases of infectious syphilis reported in Canada in 2008, 444 of which were in Ontario.
That total number was roughly 12 times higher than the 115 cases reported for all of Canada in 1997.
In recent years, there have been noticeable outbreaks of syphilis in Vancouver, Calgary, Ottawa, Montreal and Toronto, affecting sex trade workers, their partners and clients, heterosexuals and men who have sex with men.
In Toronto, according to city statistics, there was a 1,000 per cent increase in the rate of new reported infectious syphilis cases between 2001 and 2008.
