CBC Retirees Double Dipping?

As part of Brian Lilley's series on the CBC he's discovered that dozens of retirees have been hired back as consultants or contractors and of course we pay their pensions and their consultant or contractor fees. So could they be double dipping? I would say so.

OTTAWA - CBC hires back dozens of retirees each year as contractors or consultants.
Documents obtained through access to information show that between 2005 and
2007 the state broadcaster hired 125 people who were also receiving an annuity or pension from CBC.
The records took three years to obtain and required the intervention of the federal information commissioner. At first CBC refused to release any records, claiming all records were considered personal information and not subject to the access law.
After an investigation by the information commissioner's office, CBC agreed to release the total number of retirees hired back on contract.
The practice of retirees returning to work as consultants in federal government departments is not uncommon in the federal government and is often referred to as ³double-dipping.² In 2005 CBC hired back 21 retirees, 37 in 2006 and 67 in 2007.

Wouldn't  Mr. Braaa.....dcast Don Newman former host of the old CBC Politics show come to mind as one of those "retirees" that have been hired back?  Because he now writes a column on the CBC website and appears on panels etc on CBC television from time to time. How much is he and others sucking out of the taxpayer by doing this?  I would like to know. He's probably receiving a pension and collecting a fee or a salary or whatever.    I hope when the information committee investigates the CBC after the Christmas recess, we  can find out.
