Opening (1952) The track was opened in 1952 by Hugh Brodie as a dirt track and operated as such until it became a paved oval in 1960. Expansion to its present-day paved track configuration took place in 1969.
Super Modifieds (1970s) The asphalt surface is said to have been specifically built to accommodate super modified racing. The "Supers" raced at the speedway from the 1970s through the 1980s before being dropped from the racing card and replaced with Super Late models. Super Modified racing did not return to Delaware Speedway until 2006 when the
International Supermodified Association (ISMA) touring series made a stop. The series continued to attend the track until 2019.
CASCAR era (1981–2005) The history of
CASCAR and Delaware Speedway are very closely connected together. Delaware is widely recognized as the "Birthplace of CASCAR". The promoter of CASCAR, Tony Novotny was simultaneously promoter of both CASCAR Operations and Delaware Speedway before selling the track in 2001. The track hosted
CASCAR Super Series races from 1986 until 2005 when Delaware Speedway dropped CASCAR from its schedule in the same year the track left the
NASCAR Dodge Weekly Series after a two-year membership. The reason for the drop was delays in the delivery of the CASCAR schedule, prompting Delaware to fill the 2 annual CASCAR dates with its own events. Observers also cited strained relations between the track and CASCAR over the series' operations being controlled by its impending buyer NASCAR. All of the CASCAR Super Series' races in 1986 were held at the track, Ken Johnston was the champion.
NASCAR Dodge Weekly Series (2004–2005) Delaware Speedway became the first Canadian track to be a member of the
NASCAR Dodge Weekly Series in the 2004 season. At the conclusion of the 2005 racing season, the speedway cancelled its NASCAR sanctioning at the same time as it dropped its CASCAR Super Series events. During the period after a series of rainouts and under the NASCAR rules at the time, the speedway was forced to run a number of double feature nights to make the minimum number of races required under the NASCAR program. With double feature nights increasing the weekly payout and not increasing the number of fans, the speedway reconsidered its place within NASCAR.
Independent period (2006–2008) Following the end of NASCAR sanctioning the speedway management set about a focus on building the profile of its weekly racing programs. The track worked with the Ontario-based inter-speedway organization Weekend Warrior Series (WWS) in an attempt to increase travel between Ontario-based speedways and also introduced new Late Model events such as the annual Canada Day PartSource 140 and giving the former CASCAR 300-lap Labour Day race to the division. At the beginning of the 2007 racing season the track General Manager and Operations Director resigned from the speedway. Jeff Wilcox was put in place as Operations Manager and the 2007 race season went ahead as scheduled. Wilcox would remain operations manager until the conclusion of his term at the end of the 2008 racing season.
New ownership and return to NASCAR (2009–2011) On January 21, 2009, the speedway formally announced that one of the business's part owners, Arlen Scherba, had bought out the other business partners to become the sole owner of the speedway business. In the same release, the track announced its return NASCAR weekly sanctioning under the NASCAR Whelen All-American Series banner. The release also indicated that the speedway land lease was no longer a concern. A new operations manager had been put in place before the new year, Paul Houghton, who had previously directed the track's Junior Racing League (JRL) program. Jeff Wilcox continued his role as Race Director, and John Houghton continued as Public Relations manager. Joe Czernai would later be added as the track's general manager, part way through the season. The speedway successfully executed its first NASCAR Canadian Tire Series event on Saturday, June 6, 2009, and repeated the event one year later on June 5, 2010.
D. J. Kennington was the winner of both events. The 2009 season also featured numerous track renovations including repaving the majority of the front stretch, new corner lights, and electronic timing and scoring as well as a new ticketing system. The 2010 Delaware Speedway season schedule was similar to that of 2009, with the addition of a special Summer Showdown featuring NASCAR drivers Kyle Busch, David Reutimann, and Jason Leffler. The event was won by Kyle Busch and was his first win in Canada. The 2010 schedule reduced the Open Wheel Modified series to a smaller schedule as part of retooling efforts for the weekly program, while increasing the number of races for Late Models, Super Stocks, and Trucks. In 2011, the track hosted a
NASCAR Whelen Modified Tour event in September. It also announced plans to expand seating capacity by 600 and replace a number of grandstands to accommodate larger events, but the installation of those grandstands was put on hold shortly after the announcement to make additional preparations. Ron Sheridan, champion in the track's Late Model class, took over as race director in December 2010.
DeMelo–Spivak partnership (2012–2021) On December 1, 2011, Arlen Scherba withdrew as owner of the track and the DeMelo and Spivak families became owners of the speedway. The change in ownership was considered historically significant as it represented the first time the lease-holding Spivak family was to have a direct interest in the speedway business.
The Delaware Group (since 2021) A new ownership group, The Delaware Group, consisting of Walt Spivak, Jon Aarts (John Aarts Group/J-AAR) and the United Racing Series (Ivor Jones, John Jones and Luke Ramsay) now oversees the track with Dave Graham managing operations under the role of General Manager. Luke Ramsay has assumed the position of President of Delaware Speedway with Darryl Timmermans in the role of Competition Director. The United Racing Series marketing and management team promotes the speedway. The new ownership group significantly invested in the facility including racetrack surface upgrades that began at the conclusion of the 2021 race season. and they owned the half-mile oval ever since 2021. == Events ==
