In 2013, the 100th Regiment Historical Society, a not-for-profit organization, decided to re-raise the regiment as an historical interpretation program with the goal to:
- Promote the memory of the original regiment.
- Operate a program for youth that stimulates an interest in history.
- Advance education.
Based in Ottawa, Ontario, and active throughout the year, the modern regiment is dressed, equipped, and performs foot and arms drill in a manner that accurately reflects the original unit as it would have appeared in garrison during the summer of 1815. Unlike the original regiment, both men and women are permitted in the ranks and can take part in activities.
Since 2015 and in partnership with Parks Canada, the regiment spends much of the summer months at the Rideau Canal’s Ottawa Locks located downtown between Canada’s Parliament buildings and the Chateau Laurier. The Rideau Canal is both a National Historic Site of Canada and a UNESCO World Heritage Site. In May of 2016, the regiment began performing on Parliament Hill at the War of 1812 Monument throughout the summer.
