Condition before the project

View photos to see examples of some of the concerns and spaces being addressed as part of the Centre Block project.

Rust-coloured stains covering a stone carving of a man on a horse.

Some stone carvings were damaged by water leaks.

A stone ceiling that is black from water damage and there are cracks patched with mortar.

Water infiltrated through many sections of the roof and windows of the Centre Block over the past century. Water damage cracked and discoloured parts of the ceiling of the House of Commons Chamber North Gallery. We are repairing this and other heritage features as part of the Centre Block project.

A concrete column in the basement of the Peace Tower that shows signs of erosion at its base.

The concrete that supports the historic Centre Block building was deteriorating and needed to be reinforced. This column in the basement of the Peace Tower that provided structural support has weakened from erosion.

A brick wall in the attic covered in white salt crystals.

One of the problems that affected the Centre Block was that water infiltrated through the masonry walls. Efflorescence is a fine, white, powdery deposit of water-soluble salts left on the surface of masonry as water evaporates. The white pictured in this photo means that water was coming in through the wall in the attic where the photo was taken.

A steel beam inside a masonry wall. The beam is rusted and corroded.

Steel on the exterior and interior of the building was rusting and breaking down. In this photo, you can see the corrosion of structural steel in a masonry wall.

A green copper roof that is dented and damaged.

Centre Block’s iconic copper roof needed to be replaced. This photo shows damage to the roof. This damage can cause water to leak into the building. As part of the restoration, we are replacing the copper roof.

A fireplace with a carved stone mantelpiece.

When the Centre Block was built, it was common to heat offices with wood-burning fireplaces.

An old ventilation system in a basement.

The ventilation system was at the end of its useful life and needed to be replaced.

Pipes in a basement show visible signs of rust and corrosion.

The water and heating pipes in the building were original from the early 1900s. They needed to be replaced. These water and heating pipes in the basement of Centre Block leaked and were patched many times. Rust on the old pipes caused the leaks and made them difficult to repair.

A stone carving of a beaver holding an oak branch. The stone has rust-coloured stains and is faded and broken at the bottom.

Salt, water and the continual freeze-thaw cycle damaged the sculptures on the exterior of Centre Block. This is outside the entry of the Peace Tower. Over time, if left unchecked, the sculptures and the stone around them would disappear. As part of the Centre Block project, we are restoring damaged sculptures so they will last for future generations.

Cracks in decorative stone patched with mortar.

Our masons did the best they could to repair cracks in the Centre Block stonework, but many features, such as these cracked stones in the Memorial Chamber, needed to be removed and replaced.

A hand removing a broken piece of stone from a masonry wall.

The mortar between Centre Block’s stones was crumbling. In some places, stones could be removed by hand. Water infiltration eroded the mortar. As part of our project, we are removing the stones and repointing them with fresh mortar.

Work being done

View photos of the work we are doing to restore and preserve Parliament Hill's majestic Centre Block building.

Four workers wearing protective equipment remove a painting from a wall and wind it onto a large spool.

Fine art conservators carefully remove the murals in the former Reading Room. Mural artist Arthur Crisp painted the 17 panels in the early 1920s.

A man in a hardhat on scaffolding looks at carved stone and consults a tablet computer.

A masonry conservator assesses the condition of stone friezes carved in the House of Commons foyer.

A worker measures a panel of a stained-glass window that is on a table.

Conservators trace, photograph and assess stained-glass windows removed from the House of Commons Chamber. The stained glass is being packed and will be cleaned and repaired as part of the Centre Block project.

A worker wearing personal protective equipment lays samples of old wallpaper removed from walls onto a table.

A conservator removes and assesses wallpaper in one of the rooms of the Centre Block.

Workers in protective coveralls move a slab of marble.

Workers remove decorative marble slabs from the wall of a room in the Centre Block. They are wearing equipment to protect them from any hazardous materials that may be located behind the walls.

A worker on scaffolding consults drawings and takes notes on a pad of paper. There is a coffered ceiling overhead.

A heritage woodwork specialist consults plans and prepares to remove an oak wood coffered ceiling in the Centre Block.

Two workers in protective coveralls lift a brass mailbox that reads "Royal Mail Canada."

The Centre Block's built-in brass mailboxes are removed and will be repurposed as part of the project.

A man in a hardhat holds a 3D scanner over a stone carving. There are white dots on the stone carving.

A digital imaging specialist does a 3D scan of a stone carving removed from the Senate porch entrance. The dots on the carving serve as reference points when a digital 3D model of the stone is being created.

Three workers wearing protective equipment remove painted fabric from a ceiling and wind it onto a large spool.

The ceiling of the House of Commons Chamber is decorated with painted linen. A conservator carefully removes the fabric and rolls it up to protect it.

A worker lays a silicone mould on the floor.

The Centre Block has much ornate plasterwork. Workers clean each unique section of plaster to reveal its original beauty. They then make silicone moulds of each of those unique sections. If a section of plaster needs to be removed so the structural elements of the building can be accessed, it can later be reproduced. Here, a plaster specialist makes a silicone mould of plaster friezes in the Senate suite in September 2020.

Two workers attach straps to a bronze statue of a soldier.

We are removing anything that can be removed from the Centre Block. We are protecting in place heritage elements that cannot be removed. Here, workers are removing the Baker Memorial from the House of Commons foyer. This statue commemorates the life, dedication and sacrifice of Lieutenant-Colonel George Harold Baker, a sitting member of Parliament killed in action during the Great War.

Two workers guide the lifting of a masonry stone by crane on a construction site.

We protected in place the heritage elements that could not be safely removed. Here, workers install plywood to protect the First World War altar in the Memorial Chamber.

An archaeologist sifts through dirt during an archaeology dig.

Archaeologists studied the history of the site, identified high archaeological potential zones and proceeded with investigations and excavations that unearthed thousands of artifacts. In this photo from October 2019, an archaeologist sifts through dirt to look for artifacts.

Workers on scaffolding gently lower a large painting to the floor.

Conservators move and store 1 of 8 historic First World War paintings from the walls of the Senate Chamber. The paintings are more than 3 metres wide and 2 metres high, so they needed to be moved and stored with great care. This work was done in May and June 2019.
