Chuck was born and raised in Norwood where he played his junior hockey. Chuck took advantage of his poor social life to put in extra practice and develop his hockey skills. Unhappy at not being drafted by the NHL or WHA, Chuck was a walk-on at a Red Army rookie camp and made the team in 1980. Lucky enough to be paired with Don “Magic” Moreau, Chuck and Don were on two of the more famous Red Army lines. The ill-fated SAM line (Neil Strange, Asselin and Moreau) was quickly broken up after opposition teams realized that the SAM line couldn’t handle the rough going. Neil was unceremoniously dumped by his brother (Coach Greig Strange) and replaced by Bill Kastner forming one of the most famous lines in Red Army history - the MAK line. Chuck and the MAK line dominated opposition teams until Magic retired from active play in the late 1980s.

Early in his career, Chuck was known as a “prima donna” and “delicate” player. Even today, with all of his injuries and surgery he has a hard time shaking the "delicate" label. In the winter of 2003-04 Chuck had his right shoulder reconstructed and the hump removed. Chuck claims that this will reduce the expected number of injuries next season by 20%. "I don't expect to be carried off the ice more than 4 or 5 times" he stated in a press release.

In 1986, Chuck and Mike Teillet started the Red Army Brewing Company. Chuck designed the famous Red Army Lager beer label that was instrumental in launching the beer into the success that everyone is familiar with. Chuck has capitalized on his success, creating an endorsement empire. The most famous is probably his line of specialty condoms, especially the famous “Charles Asselin Stubby”. In 1993, Chuck finally accepted a long-standing offer to become an instructor at Artie's Hockey School. In 1999, Chuck moved up to the front office, as General Manager of the Red Army - on the condition that he could remain playing.
