A former Liberal senator will spend six months in jail for fraud he committed while working in the Red Chamber.

Raymond Lavigne was also ordered to serve six months of house arrest and to donate $10,000 to charity, after being convicted of fraud and breach of trust charges in March.

The 65-year-old Lavigne resigned his Senate seat shortly after his conviction.

At his sentencing on Thursday, Lavigne could have faced up to 14 years in prison. But the Crown had only asked for a sentence of 12 to 15 months.

Crown prosecutors pointed to Lavigne's motivation for financial gain, his repeated transgressions and his lack of remorse as aggravating factors in his sentencing.

But Lavigne's lawyer said his client's reputation had suffered greatly a result of the charges and also that he had repaid some of the money.

Lavigne indicated Thursday that he plans to appeal his convictions and sentence.

"It's not justice," Lavigne muttered when leaving court.

Lavigne was appointed to the Senate in 2002 when Jean Chretien was still prime minister.

He was elected as a Liberal MP on three occasions before being named to the Senate.
