By the early 1990s, neither the piers nor the ironwork had been properly renovated since their construction; salt from the street, the freeze-thaw cycle, and pollution had damaged and disintegrated the grout and stone faces. Thus, in 1992, Public Works and Government Services Canada began a $5 million restoration project of the entire fence along Wellington, which included the Queen's Gates. The piers were fully repointed and stabilised, including their foundations, and the gates were restored and partly rebuilt by a blacksmith.[2]
