Liebrock was born on May 24, 1945 in Windsor, where he would later stand out as a high school football player. He attended Grade Nine at Forster Collegiate and his remaining years of high school at Patterson Collegiate. Under coach Al Newman, Liebrock stood out for the Patterson Panthers on both offence and defence. A punishing blocker, he was twice named First Team All-City and won the WSSAA Championship in 1962.

Liebrock attended St. Mary’s University in Halifax, which he led to a second-place football finish in 1963. The following year, playing with the Windsor AKO Fratmen, he reached the Eastern Canadian Finals, losing eventually to Montreal Notre Dame.

In 1965 and ’66, Liebrock attended Hillsdale College in Michigan, where he started on both sides of the ball as an offensive guard and linebacker. After standing out in a game against Northern Illinois University, he was recommended by a member of the opposition’s coaching staff to Knobby Wirkowski, General Manager of the Toronto Argonauts. The Argos took Liebrock as their first Canadian pick in the 1967 Canadian Football League entry draft, beginning for him a professional football career that would last until ’77.

Chuck Liebrock played 11 years in the Canadian Football League in the 1960s and ’70s, three with the Toronto Argonauts and the remainder with the Winnipeg Blue Bombers. Liebrock spent his entire career as an offensive right guard and occasionally played linebacker on the other side of the ball. At his peak, he was considered to be among the three best offensive guards in the CFL.

Liebrock played for the Toronto during the 1967, ’68, and ’69 seasons before moving to Winnipeg, where he would play out the rest of his career.

Although Liebrock never reached the Grey Cup Game, he was an Eastern Conference finalist with Toronto and 1968 and ’69, and he reached the Western finals with Winnipeg in ’72.

Liebrock struggled with injuries for most of his career. In 1971, he missed nine games after suffering a broken leg. Due to chronic ankle problems, Liebrock needed to have his ankle frozen before every game between 1972 and ’77.Playing in the Western Conference, Liebrock competed against a litany of future CFL Hall of Fame players, including Edmonton’s Dan Kepley and John Legrone, Calgary’s Wayne Harris and John Helton, and Saskatchewan’s Ed McQuarters. Playing on the right side of the offensive line, Liebrock was generally asked to block the opposing team’s strongest defenders.

In 1968, Liebrock shared the Argonaut’s Top Canadian Award with Dave Knetchel. He was Winnipeg’s nominee for the Schenley Award, for the best Canadian player in the league, in 1972.

Following his career, Liebrock, who had always worked in sales, was a regional manager for various Winnipeg television stations. In 1985, he took a job as General Manager with Mid Canada Television (MCTV). The job saw him move to Sudbury. He still lives in the city, where he was worked as Business Manager, Northern Ontario for Petro Canada since 1990.
