Canada's Worst Driver 4 is the fourth season of Canada's Worst Driver, a Discovery Channel Canada television series which seeks to improve the driving of eight nominated contestants, each of which trying to avoid being named Canada's Worst Driver. Like previous series, each contestant is nominated by a loved one, and are taken to the Driver Rehabilitation Centre, located this year at an abandoned correctional facility in Guelph, Ontario. At the rehabilitation centre, each contestant is taught key driving skills, and are tested in various challenges, with three challenges to an episode. Before each challenge, host Andrew Younghusband performs each challenge to demonstrate that they are doable without error by an average driver. The first episode, where the contestants must drive to the Driver Rehabilitation Centre from a location an hour's drive away in the traditional first challenge, serves as a skills evaluation. Starting with the second episode, and at the end of every episode thereafter, the experts and Andrew decide on which of the remaining contestants have been sufficiently rehabilitated to be let go onto public roads. This continues until three contestants remain, where two traditional final challenges determine who is named Canada's Worst Driver. Though normally one contestant leaves in every episode, the experts may, at their discretion, refuse to allow anyone to graduate, or conversely graduate more than one contestant in an episode. In extreme circumstances, the experts may also choose to expel a contestant with no intention of improving their driving skills. This year, like the previous season, roughly half of the challenges are new to the series, while the other half, such as the initial drive to the Driver Rehabilitation Centre, the Eye of the Needle, the Water-Tank Challenge, the Mega-Challenge, and the series-ending road test, are returning from previous seasons. However, the challenges this season are more specifically tuned for the individual contestants than in previous years, to better address driving issues specific to each contestant. For this year, a fleet of brand-new luxury cars have been commissioned for some of the challenges.
