OTTAWA — The cost of renovating Parliament Hill is expected to hit $5 billion by the time the 25-year project wraps up, CBC reported Monday.

According to documents released by the Department of Public Works, the repairs to almost every building on Parliament Hill, originally pegged to be $460 million in 1992, will have ballooned to more than 10 times that amount upon completion.

Renovations started on the aging buildings in 1992, when builders began renewing Parliament’s West Block. The project was shelved in 1998, then restarted in 2005, with an estimated budget of $769 million. That total has since risen to more than $1 billion, according to CBC.

The cost of that project included $24 million spent to build four temporary Commons committee rooms while the others are repaired in the West Block.

CBC also reported that the Conservative government has resurrected a plan from 2001 to construct a new building on Parliament Hill.
