Gatineau police say the 68-year-old man was arrested in February and charged with sexual assault, sexual exploitation by a person in authority and incest.
The incidents reportedly happened between 1991 and 2005 while the daughter was between the ages of 18 and 32. Police said she relied on her father for care during that time.
The woman is now living with another family member, police added.
CBC News is not reporting the name of the accused in order to protect the victim's identity.
Victim came forward, contacted police
The victim came forward and made a complaint to police in January.
Her interviews with police and the investigation that followed led to the man’s arrest on Feb. 10, police said.
The man was charged in February and released on a promise to appear in court. He is banned from making any communication with his daughter.
Police are also calling on victims of sexual assault to reach out for help by contacting them at one of the police stations or by calling 819-246-0222.
