Hart was born in Montreal, Quebec. He grew up in Montreal, Spain, Mexico City, and Key Biscayne, Florida, and was raised solely by his mother from the age of 10 when his parents divorced. At 13, he sang for Tom Jones and recorded with Paul Anka in Las Vegas and, at 19, recorded demos with Billy Joel and Eric Clapton before signing to a major label at the age of 20.

Hart's first album was recorded in Manchester, England in the spring of 1982. Released in 1983, First Offense, featured the US Top 10 hit songs "Sunglasses at Night" and "It Ain't Enough". The album went platinum in both Canada and the United States.

His follow-up album was the chart-topping Boy in the Box. Boy in the Box reached diamond status in Canada (one million copies sold), becoming only the second Canadian album to do so, after Bryan Adams' Reckless that same year. It featured the radio hit "Never Surrender," which was the #2 song in the year-end Canadian charts in 1985, finishing second only to "Tears Are Not Enough," the Northern Lights charity single which also featured Hart.

Hart recorded songs even after his commercial success in the United States began to wane. However, he continued to be successful in Canada throughout the 1990s. He amassed 26 Top 30 hits in his native country.

In 2002, Hart returned to the studio to re-record "Sunglasses At Night," which was remixed by engineers, Original 3. Released to club DJs that year, it became an instant smash on the international dance music charts.

Today, Hart is based in the Bahamas with his wife, French-Canadian singer Julie Masse and their four children: daughters India, Dante, and River and son Rain. Masse, born on June 3, 1970, was the inspiration for Hart's song "Third of June."

Hart currently works primarily as a songwriter, writing music for his wife and other artists, including Celine Dion.
