The Roseisle War Memorial commemorates soldiers from the local area who served in the First World War, Second World War, and Korean War. The hand-carved marble First World War plaque was originally erected in the Roseisle United Church in the Rural Municipality of Dufferin. The plaque was completed in 1915-1916 through a group of women called the Khaki Club. There were also two Second World War paper plaques in the church. When the church closed in January 1971, the plaques were placed in the Memorial Room in the Carman Memorial Hall. The Memorial Room was dedicated to servicemen killed in action. The plaques were then moved to the Carman Legion.
The former site of the CN station was acquired by the Rural Municipality of Dufferin in 1987, for a memorial and a working committee was established. Murray Billings of Carman Granite Marble Works spent a great deal of time acquiring marble from Italy for the Second World War plaques so they would match the First World War plaque. Eldon Fields completed the brick work for the memorial. The memorial presents an entirely familiar building element – a brick wall—abstracted by the use of pillars at the edges and elegantly curved transitional elements. Funds for the memorial were raised from families of Veterans, the Carman Legion, and the Miami Legion.
Repairs were made to the plaques in 1997 and again in 2017-8. Both were funded by local donations and legions, and in 2018 the community received a grant through Veterans Affairs Canada. Through the grant, Carman Legion, Miami Legion and Rural Municipality of Dufferin, the Roseisle War Memorial Committee members had repairs done to the memorial in 2018. It was in need of repairs after years of sun, wind, rain, and snow, had stripped some of the paint from the memorial.
A rededication ceremony was held on October 6 2019 to honour those listed on the monument, as well as the community members involved in having the names repainted and the cenotaph repaired. Rural Municipality of Dufferin Reeve George Gray and Midland MLA Blaine Pedersen attended the rededication.
In 2019, the committee started fundraising for a canopy to protect the cenotaph and the canopy was built in 2020.
