The former head of nuclear medicine at the Jewish General Hospital, previously convicted of sexual assault, is now facing 10 additional charges in connection with complaints from seven new victims.
Stephan Probst, 47, was arrested on Thursday and charged with sexual assault, assault and administering a substance to incapacitate a victim.
He allegedly assaulted his victims between 2003 and 2020.
One of the victims has still not been identified, according to court documents.
Probst was out on bail when he was rearrested on Thursday.
Last year, Probst and his girlfriend, Wendy Devera, were convicted of sexually assaulting a young woman they met online in 2020.
The victim claimed she was drugged, and while she had agreed to have sex with Devera, she said she never consented to sex with both of them.
Probst and Devera are still awaiting sentencing and could face lengthy prison terms. They are both appealing their previous guilty verdicts.
