Sen. Patrick Brazeau in critical but stable condition after surgery

HULL, Que. — Quebec health officials say Sen. Patrick Brazeau is in critical but stable condition in hospital after successful surgery.

A health institution in western Quebec says in a statement Brazeau's life is not in danger and that he was admitted to hospital in Hull early this morning.

There are no details on the type of surgery.

Quebec provincial police say they went to a residence in Mayo, Que., late Monday night to support ambulance technicians and that there is no criminal investigation.

Brazeau was granted an unconditional discharge last October despite having pleaded guilty to reduced charges of assault and possession of cocaine.

A more serious charge of sexual assault was dropped due to a lack of evidence.

Brazeau still faces a criminal trial for fraud and breach of trust arising from his Senate living expenses, scheduled to take place in March 2016.

He was kicked out of the Conservative caucus after he was charged and put on leave with pay. Months later, he was suspended without pay over the expenses issue along with Mike Duffy and Pamela Wallin, but that suspension was lifted when Parliament was dissolved for last fall's federal election.

Brazeau remains on leave with pay from the upper chamber, and his salary is being clawed back to repay nearly $50,000 in disallowed housing expense claims.
