Apparently the revenuers in Canada are just as inept and/or corrupt as their IRS counterparts in the United States.
In 2007 the Canada Revenue Agency issued a $381,000 rebate check to then-imprisoned mob boss Nicolo Rizzuto at the time it had a lien on his home for $1.55 million in unpaid taxes, and "two former auditors say they witnessed an attempt to stall a corruption probe and colleagues getting cozy with organized crime" as reported by CBC.
Nicolo Rizzuto was gunned down through a kitchen window during supper by an outside sniper in November 2010 as part of an ongoing turf war among rival clans for the drug trade in Montreal.
The Charbonneau Commission currently is investigating claims that the Montreal Mafia and dirty politicians are taking cuts from government contracts to construction companies in a massive bid rigging scheme, and the panel has subpoenaed Nicolo's son Vito Rizzuto to appear as reported by Monique Muse for The Montreal Gazette.
