About 550 Canada Revenue Agency employees in Ottawa — and 2,000 across the country — are receiving workforce adjustment letters today as part of a major restructuring at the federal agency.

The tax agency's plan to streamline processing activities will see two specialized Ottawa sites gradually consolidated to CRA's seven other processing centres.

The full-time employees work in taxation and processing centres.

Workers will have six months to decide whether to take a job at a tax centre in another part of the country or accept a new post in an office within a 40 kilometre radius.

Robert Campbell, the president of the Union of Taxation Employees, said in a statement the union wasn't consulted on the workforce changes.

The readjustments will take place over a two-year period.
