1994, the Peace Tower was covered and the accessible spaces closed for a two-year conservation project aimed at reversing deterioration of the masonry and preventing further moisture penetration. However, the machinery of the clock was not within the scope of work and, on 24 May 2006, the clock stopped for the first time in 28 years, with the display inactive at 7:28 for about one day. Beginning in 2022, the Peace Tower clock chimes and carillon will remain silent until about 2027, as the entire carillon is to be dismantled and restored.
