Here's an article about the same guy getting released in 2014: https://www.thespec.com/news/stoney-creek-residents-fight-relocation-of-sex-offender-keith-theodore-constantin/article_589b5b81-454f-5beb-91be-2950d52dccd9.html
Here's another article about him getting arrested again shortly after that: https://www.cbc.ca/news/canada/hamilton/headlines/convicted-sex-offender-keith-constantin-arrested-again-1.2726024
Here's another article about him getting released again a year later: https://www.yorkregion.com/news/schomberg-residents-on-edge-over-release-of-high-risk-offender/article_37eaeef3-e3ec-5110-bc53-706b6970e66c.html
Obviously he got arrested again at least once at some point because here we are talking about him getting released again.
Also from that 2nd article: "He was also convicted in 2000 of sexually assaulting a young boy and of sexually assaulting a 45-year-old blind woman in separate incidents." So this goes back even father than I what I can find just on google. Serial rapist catch-and-release for over two decades. Canada's legal system is a joke.
