Born in Montreal, Canada in 1998, Stroll was bitten by the racing bug aged five when his father, eminent businessman and occasional amateur sportscar driver Lawrence Stroll, bought him a go-kart.
He won his first race and championship three years later, before being selected for Ferrari's prestigious Driver Academy in 2010 following more karting success.
Stroll stepped up to single-seaters in 2014, competing in the Florida Winter Series before winning the Italian Formula 4 championship at his first attempt. Another title, in New Zealand’s Toyota Racing Series, followed in early 2015 before a learning year in European F3 in which he finished fifth with one win, but also had a couple of heavy crashes.
There would be no such problems in the same series in 2016 as, newly hired by Williams as a development driver, he triumphantly claimed the title, picking up 14 victories, 20 podiums and 14 pole positions along the way.
A month later, Williams confirmed him as half of their race line-up for 2017.
