After graduation, Chan was accepted into a technical institution and, attracted by the 3,000 HKD monthly income, also joined TVB's Artiste Training Class.

His father initially refused, but later gave in when TVB offered an automatic contract cancellation if Chan didn't do well in his classes.

Chan's television debut was in the serial drama Instinct in 1994, where he briefly appeared as the young friend of Ekin Cheng's character Pao Man-lung.

Weeks later, he made a brief appearance in the sitcom A Kindred Spirit as the friend of Andy, portrayed by Hawick Lau, who was Chan's training class classmate.

"[3] Despite his past acting experiences in both television and film, ATV only gave him minor roles and spots in music videos.

In 2011, Chan garnered media attention and critical acclaim for his portrayal of barrister Keith Lau in the television legal drama The Other Truth.

Chan's subsequent performances won him critical acclaim, most notably in Brother's Keeper (2013), Ruse of Engagement (2014), and Captain of Destiny (2015), the latter winning him the TVB Anniversary Award for Most Popular Male Character.

In 2016, while a guest judge for Miss Hong Kong, he met contestant Phoebe Sin and subsequently in March 2017, was photographed in a car with her on The Peak.
