The Ontario Regiment (RCAC) Museum is a military museum located in Oshawa, Ontario, Canada. The museum is located on the South Field of the Oshawa Municipal Airport, 1000 Stevenson Rd N, Oshawa, Ontario (50 km east of Toronto, Ontario).

The museum is composed of a static section tracing the history of the Ontario Regiment, and a "Vehicle Section" with more than 100 operational military vehicles, including jeeps, trucks and tanks, making it the largest collection in North America.

The museum restores, preserves, displays, and commemorates the service of the Canadian Armed Forces (with an emphasis on the Royal Canadian Armoured Corps and its vehicles) and its role in the history of Canada. It does this through using artifacts to tell the story of the Ontario Regiment from 1850 to the present day and its collection of historical military vehicles to "bring history to life." The museum seeks to honour those who came before and those who are currently serving and to make the history accessible to the public in an engaging, relevant, and exciting way.

The museum is a non-profit organization with two full-time staff and more than 140 volunteer members. These members act as guides, drivers, and maintainers of the vehicle collection, as well as the first line of restorers to bring historic vehicles back to life.

The museum is a proud member of the Durham Region Community and is often supported by members of the Ontario Regiment, the Ontario Regiment Cadet Corps, Royal Canadian Legion Branches 43 and 637, and 420 Wing (Oshawa)–Royal Canadian Air force Association.

The museum is also supported by the Royal Canadian Armoured Corp Association (Cavalry), the Royal Canadian Armoured Corps, and the Canadian Forces Directorate of History and Heritage.

The museum is housed on the South Field of the Historic Oshawa Executive Airport. The airport opened in June 1941 under the British Commonwealth Air Training Plan as No. 20 Elementary Flying Training School RCAF Station Oshawa. Only three of the original buildings are still standing. Potential military pilots from Commonwealth and Occupied countries were trained in this field. There is one primary museum building composed of the Static or Museum Section, three workshops (not open to the public), a vehicle bay, and the Military Vehicle Conservation Centre. The Museum has the use of two other building but these are not open to the public.

The Museum Section documents the story of the Ontario Regiment RCAC from its beginnings in 1866 as the 34th Ontario Battalion of Infantry, through WW1 as the 34th and 116th Battalions, 11th Armoured Regiment (The Ontario Regiment (Tank)) in WW2 and the Ontario Regiment (RCAC) today. Members of this regiment have served Canada in every military operation since the Fenian Raids.

The museum recounts the history through the display of artefacts grouped by type and period - Pre-Confederation, South African War, WW1, WW2, Afghanistan. These artefacts include uniforms, personal items, weapons (deactivated), medals, pictures, and trophies. The Museum Section can be enjoyed by the visitor alone, but the use of a guide is recommended to get some of the backstories behind the artefacts.

The Military Vehicle Conservation Centre was added on in 2018 and provided an additional 15,300 square feet for the vehicle collection. While in this section of the museum, visitors will experience the largest operational, historical military vehicle fleet in North America and teams of volunteers maintaining and restoring them.

The vehicle collection started in 1976 when the then Honorary Colonel of the Ontario Regiment, Norman Wilton, purchased nine Ferret Scout Cars for use as a ceremonial troop. The original nine cars soon grew with the addition of BART - M4A2(76) W HVSS. Bart was acquired after WW2 from the US and was used as a training vehicle by the Ontario Regiment until the mid-1970s. Since then, the vehicle collection has continued to grow. Some (but not all) of the current inventory are:

Since December 2022, a new exhibit features a rare WW2 Howitzer Motor Carriage M7B1, often referred to as the M7 Priest. More than 4,000 of the U.S.-made M7 Priests were built during the war. The tank was used by the Americans, the British, the Canadians and the Free French. Many of the Canadian soldiers who stormed Juno Beach on D-Day advanced in M7 Priests.

The museum holds special events where the public can watch vehicles of the collection in motion. These include Tank Saturdays and the internationally recognized Aquino Weekend.

Tank Saturdays are single-day events, normally on the second Saturday of each summer month (May to October). These are themed events with a one-hour display show based on that theme. Often, re-enactors will be a part of the show. Armoured vehicle rides are usually available. Tank Saturdays conclude with a "Battle Royale" where two tanks and their crews go head-to-head in the museum's tank arena.

Aquino Weekend is a two-day world-class event held during the second weekend in June, and, from 2024, in July. There are two themed one-hour battle demonstrations on both Saturday and Sunday. Common themes are "WW2 - Western Front", "WW2 - Eastern Front", "Gulf War", and "Viet Nam". Each simulated battle consists of vehicles, reenactors, firepower and pyrotechnics. Additionally, there are vendors and static reenactor displays. Each day concludes with a "Battle Royale" where two tanks and their crews go head-to-head in the Museum's tank arena.

The Museum offers experiences in their historic vehicles. These experiences are more than rides; they can be a full experience working with the crews preparing the vehicle and a complete tour of all the crew positions.

Group or specialized tours are also available. Interested parties should contact the museum to enquire about availability.

The computer game World of Tanks is a partner of the Ontario Regiment RCAC Museum. There is a World of Tanks gaming station at the museum where visitors can play the game on fast optimized personal computers, with standard WOT vehicles or customized vehicles from the museum.
