Pamela Porter has pleaded guilty to two counts of money laundering in a fraud case involving a new Montreal hospital complex.

Porter was sentenced today to 33 months minus time served, meaning she has two years left in her sentence. Her time behind bars will be followed by a year of probation and 240 hours of community service.

The charges are tied to what police have described as the largest fraud in Canadian history, an alleged bribery scheme involving a $22.5 million payment from executives at construction firm SNC-Lavalin in order to obtain the contract to build the McGill University Health Centre superhospital.

Porter's plea was officially registered in a Montreal court this afternoon. She was arrested in Panama in June 2013 and extradited to Canada to face charges of money laundering and conspiracy.

The Crown said it will be able to recover at least $5.5 million from alleged fraud.

The judge in the case has issued a temporary publication ban on most information involving the plea.

The conspiracy charge against her has been dropped.
