The 153 individuals were arrested as part of Project Mercury, a joint effort involving the Toronto Police Service, Ottawa Police, Saskatchewan RCMP, United States Homeland Security and U.K. National Crime Agency.

Hoover police on Tuesday arrested a 37-year-old minister from Southside in east Alabama, saying he engaged in deviant sexual intercourse with a boy between the ages of 12 and 15. Toronto police subsequently launched an undercover investigation, during which Blackadar says officers "observed the live abuse of a six-year-old child over the internet" in July of 2015.
"It's important to understand that this is happening to children all over the world", Toronto police Staff Supt.
In March 2016 Toronto police also discovered "child abuse material" of a sexual assault of an 8-year-old.
Police say within hours the child was rescued and the abuser was caught in Pennsylvania.
One of the alleged perpetrators in that case was arrested in Pennsylvania, the other in Saskatoon, Blackadar said, adding Canadian authorities are now working to have the Saskatchewan man branded a risky offender.
"Unfortunately this was not the first time this happened, but I can tell you it was the last", Blackadar said. RCMP identified the individual in the video and rescued the child from an address in Saskatoon.
City investigators ultimately arrested him and laid a total of 10 charges, at least some of which he was ultimately convicted of, police said. Seven arrests have been made in Toronto, two in Ottawa, and one each in Belleville, Thunder Bay, Quebec, Edmonton, Newfoundland, New Brunswick and Saskatoon.
