The Quarter Century Club (QCC) was created in 1968 at the insistence of Mr. Harry H. Milburn who joined the Department of National Revenue in 1942 to introduce tax deductions at source. Throughout his career as a public servant, Mr. Milburn was always a strong promoter and supporter of staff activities. He felt strongly that the friendly associations developed among long-serving taxation staff should continue in some form after their retirement. As a result, Mr. Milburn asked one of his senior advisors to set up an organization to help preserve the links amongst retirees and those still in the workforce - resulting in the creation of the QCC.

The main objectives of the QCC were to provide opportunities for long-service employees to meet occasionally with retired work associates for the purposes of fellowship and contact retention; and to provide a variety of services for retired employees.

In the 1970s, the creation of the Data Centre led to many staff transfers from across the country. This, coupled with an increase in the number of employee transfers between district offices and Head Office, led the QCC to extend its membership to those who had 25 years of service as long as they had worked in Head Office for a period of time in the 1970s. This was later changed in the 1980s to include all employees in the National Capital Region with 25 years of service.

In the fall of 1986, at the 19th Annual General Meeting, the QCC constitution was amended to be more inclusive, allowing for the annual election of directors from a candidate pool that included both retirees and employees, as opposed to a previous majority of retirees. At the same meeting, the QCC became known as the Capital Region QCC instead of the Head Office QCC, and membership was redefined to include employees from both the Ottawa Taxation Centre and the Ottawa District Office. The purpose and objective of the Capital Region QCC became more general and the provision of a variety of services to retired employees was eliminated.

Since 1979, and over the course of the years that followed, the Canada Revenue Agency agreed to provide the QCC with assistance in the areas of accommodation, limited phone use, and informing new retirees of the club objective and functions. In 2006, the Agency agreed to create and host the QCC web site and provide access to both internal and external users.

Since its inaugural gathering in 1968, the QCC has succeeded in keeping up with its mission, and has maintained their network of staff and retirees through numerous social events including curling bonspiels, golf tournaments, Christmas luncheons, and Annual General Meetings.
