Connaught Park, later known as Hippodrome d'Aylmer, was a thoroughbred, steeplechase and harness racing track, later having a casino and live betting parlor, that operated from 1913 until 2009.

The track was founded in 1913, named after the governor-general of the time Prince Arthur, Duke of Connaught and Strathearn, who was also the club's first honorary president.

The Connaught Park Jockey Club was founded by J. McEntee Bowman, a hotelier from New York city, Ed Skead and J. K. Paisley.

Directors included Thomas Ahearn, J. W. Woods, L. N. Bate, Redmond Quain, Stewart McClenahan, J. W. Carling, N. A. Belcourt, C. E. Fauqier and Clifford Sifton.

[1] The first races were held on June 14, 1913, with Sir Wilfrid Laurier in attendance, part of a seven-day meeting.

Westy Hogan, which had been stolen, was seized by Connaught, but returned to his Detroit owners for $60,000 after court action.

The daily double allowed betters to make a higher-odds bet, picking the winners of two races at the track.

The purses offered by Connaught and Blue Bonnets were not acceptable to the Horsemen's Benevolent and Protective Association (HBPA).

Joe Gorman bought out his partners for an estimated $1 million in a sale that was closed in December 1986.

[8] That same year, the Connaught Cup race, the track's premier event, was cancelled to save money.

[10] Money problems led to the Quebec Racing Commission suspending Connaught's license in March 1995.

The track owed the $317,000 to horsemen, $400,000 in taxes, $100,000 to Quebec Hydro, and a $1.6 million mortgage to Toronto-Dominion Bank.

In May 1996, retired newspaper executive Michel St. Louis and 28 other investors purchased the track for $1.2 million and $500,000 in unpaid taxes.

[16] The facilities were rebuilt with an expanded betting parlour and Loto-Quebec gambling machines and a reduced racing schedule.

[18] Hippodrome d'Aylmer's betting parlour remained open until October 9, 2009, when Attractions Hippiques sold the site to a local developer.
