The infamous Bill 11 was finalized as of July 28, 2003.

It took over three years of bureaucacy, but the infamous Bill 11, which amends the Off-Road Vehicle Act to include ATVs, was finally implemented.

.
Until the passage of this Bill, ATVs could legally operate only on Crown land, on private property with the owner's permission, or on certain designated trails managed by local or district governments, such as various railbeds in the province. As of July 28, 2003, ATVs are legal on the shoulders of many sections of Ontario's highways, excluding 400 series highways.

In addition to specifying ATV road links, Bill 11 defines an ATV in specific terms, and lays out the rules of the road. For example, ATVs must drive on the gravel shoulder, or as close to it as possible. If the speed limit for automobiles is 50 kph or less, ATVs can only travel at 20 kph; if the posted speed limit is above 50, ATVs may only travel at 50 kph. A surprising rule of Bill 11 is that no two-up riding is allowed on roads, even with the new two-up machines by Arctic Cat and Bombardier. A rider must have a valid drivers licence, as well as carry proof of off-road liability insurance. It is also significant that three wheelers and six wheelers are not officially ATVs, and as such are not permitted on roads.

Equally importantly to allowing ATVs on King's highways, Bill 11 empowers the various local governments to pass the necessary by-laws to allow ATVs on their local roads. As of June 2004, Haliburton County, including its four municipalities, implemented Bill 11 by passing the necessary by-laws in order to facilitate ATV touring within their respective jurisdictions on the various County and Municipal roads. Thanks to the foresight of Haliburton's politicians on recognizing and supporting a potentially enormous tourism product, the County of Haliburton now has a comprehensive and seamless atv trail system. This means that ATV riders can now access all trailheads from almost anywhere in the county without having to trailer. Haliburton County is the most southern jurisdiction in Ontario to officially embrace the sport whole-heartedly by declaring "ATVers Welcome...Everywhere!"
