Jason Harrow is much better known by his stage name Kardinal Offishall  was born in ScarboroughON and raised by Jamaican immigrant parents . He's a Canadian rapper, record producer, DJ, and record executive. Often credited as Canada's "hip hop ambassador", he is undisputedly regarded as one of the country's best hip hop producers, and is best known for his distinctive reggae and dancehall-influenced style of hip hop.

A native of the six, Offishall began his career in the city's mid-1990s underground hip hop scene, as a member of The Circle.  He released several independent 12" singles, a debut album (Eye & I), and an EP (Husslin'), before signing with major label MCA Records in 2000. A year later, in 2001, Offishall released his second album, Quest for Fire: Firestarter, Vol. 1, which brought about the Billboard hit "BaKardi Slang", and also another banger "Ol' Time Killin'"; both singles became his signature songs

In 2005, Offishall's third album, Fire and Glory, was released in Canada. That year, he collaborated with R&B singer Akon for the first time, starting a musical partnership that lasted until 2010. In 2007, he signed with Akon's Kon Live Distribution label, through Geffen, and released his fourth album, Not 4 Sale, the following year. Its first single, "Dangerous" (featuring Akon), became a top five hit on the Billboard Hot 100, and was certified triple platinum in Canada. Offishall released two gold-certified singles, "Numba 1 (Tide Is High)" (featuring Keri Hilson or Rihanna) and "Body Bounce" (featuring Akon), before leaving Kon Live in late 2010.  Since then, his latest singles have been released on his independent label Black Stone Colleagues Inc. In 2012. 

In 2013, Offishall became the creative executive director of Universal Music Canada's A&R team. Two years later, he released his fifth album Kardi Gras, Vol. 1: The Clash under the label.  On June 4, 2019, Kardinal Offishall released a new single called "Run" which was used as the Toronto Raptors theme song during their championship run in the 2019 NBA Finals and also serves as the first single off his upcoming album Pick Your Poison.

Last year, Offishall was promoted to senior vice-president of A&R for Universal Music Canada.   He was also a judge on the second season of Canada's Got Talent.
