(CNN) — A male Toronto emergency room doctor, who used to work at the city’s largest hospital, has been arrested on multiple sexual assault charges, Canadian police said.
Arthur Porter was charged Friday with several counts of sexual assault involving multiple victims, disguising his face with the intent to commit an indictable offence, and forcible confinement, Constable Victor Kwong said.
Porter, 55, used to work for Sunnybrook Health Sciences Centre.
Sunnybrook said Porter retired in June 2016 from his $350,000 annual salary and medical pension.
The hospital was under no obligation to report any misconduct during his employment and about 30 Sunnybrook employees are under investigation, Fraser Heston, a spokesman for Sunnybrook, told CNN.
Fraser-Heston said his law firm has already filed a claim of breach of trust against Porter.
He will not comment on the specifics of the case until he speaks with the police, he said.
“It’s outrageous that this person was allowed to continue practicing medicine for so long,” Toronto Police Det. Sgt. John Holevas told reporters Friday.
However, in Canada, the medical establishment is independent of government, so once Porter was diagnosed with cancer, it was up to his medical board to terminate his status as a doctor, which it did in 2016, Holevas said.
Porter maintains his innocence, he said.
Kwong said three incidents from 2016 were linked to Porter.
In one incident, police allege Porter sexually assaulted a 16-year-old while he was attending a house party in Toronto.
In another, police said a 52-year-old male victim told police that he was sexually assaulted by Porter in a home in Toronto.
Police have not detailed the third incident.
Sunnybrook said it takes every complaint of sexual misconduct seriously and takes steps to investigate.
“Sunnybrook has robust processes in place for receiving and investigating sexual misconduct allegations,” the statement said.
