Sentencing has been delayed on Tuesday for a man who pleaded guilty to stalking country music singer Shania Twain as the Crown renewed concerns about his health.

Giovanni (John) Palumbo, a former Ottawa doctor, pleaded guilty to failing to comply with a court order and criminal harassment earlier this month.

Palumbo, who has been in custody in Toronto since March, recently completed a three-week psychiatric assessment.

The Crown decided Tuesday that they want the doctor who assessed Palumbo to take the stand at a later date.

The defence wants Palumbo to be credited for time served while in custody, a request that could soften his sentence. They are also asking for Palumbo to be released on bail.

The Crown is pushing for a conditional sentence and probation.

Palumbo was arrested for allegedly breaking a restraining order by attending the Juno Awards where Twain was being entered into the Canadian Music Hall of Fame.

Twain testified via video link during the trial, telling the court that Palumbo's sudden appearances outside her property, as well as love letters and personal gifts from him made her feel uncomfortable.

The two days of testimony featured emotional outbursts from Palumbo, who claimed he had not realized Twain was afraid of him.

A bail hearing has been set for Wednesday at 9 a.m.
