The CRA says 15 locations were searched in Ottawa, Gatineau, London, Windsor, Laval, Montréal, and the Greater Toronto area.

The Canada Revenue Agency and Royal Canadian Mounted Police have sifted through locations in Ottawa and Gatineau, in order to collect more information in an investigation of 8.3-million in taxes evaded.

Approximately 128 members of the CRA took part in the operation to search each of the properties for evidence corresponding to the commission of offences against the Income Tax Act and the Criminal Code.

The Financial Transactions and Reports Analysis Centre of Canada, or 'Fin-Trac,' contributed information to the investigation as well. Fin-Trac is the nation's money-laundering watch-dog, monitoring movement of money in and out of the country that could indicate criminal or even terrorist-financing activity.

Under the income tax and excise tax laws, Canadians convicted of tax evasion can face fines ranging from 50% to 200% of the evaded taxes and up to five years imprisonment. If convicted of fraud under Section 380 of the Criminal Code, residents can face up to 14 years in jail.

There has not been any word on arrests made in this investigation.
