The College of Physicians and Surgeons of Alberta says Dr. Ronald Tsujikawa of Calgary admitted to living with a patient who was emotionally vulnerable.
The college says the doctor, who has been suspended for six months, was also prescribing drugs to the woman despite their personal relationship.
The college has also suspended Dr. Gordon Anderson of Wainwright for 12 months.
Anderson admitted to a consensual personal relationship that included sex with a patient.
Both doctors have been ordered to undergo assessments at a centre in Texas, complete a course on appropriate boundaries and pay the cost of investigations and hearings.
In Tsujikawa's case, a hearing tribunal acknowledged that the doctor's marriage had broken down at the time, but suggested that was not a valid reason for what happened.
"Though this is a major stressful life event, it is no excuse for a physician to lose objectivity in their relationship with any patient," the tribunal's report says.
