Works on the memorial and stage were halted after City of Canning-appointed builders, Robinson Build-Tech (RBT), were placed into liquidation.
The $2,796,855 project, which was planned to be completed before April 25, is 70-80 per cent complete, with a large portion of the stage and memorial finished.
City of Canning Commissioner Steven Cole said the City appointed RBT to construct the memorial, located behind the City's Civic Centre, as part of a normal tender process.

The City has approached the builder selected as the second choice in the tender to provide a quote and proposal to finish the project.
"The recommencement of construction and completion will be set in the coming weeks when the City has established a new project timeline with the new builder," Mr Cole said.
"The memorial and stage will be open for the Remembrance Day Celebration later in the year and we hope to have construction completed well in advance of that event."
Mr Cole said there would be some additional costs associated with the appointment of a new builder.
Canning Districts RSL secretary Terry Reynolds, who served in the army, navy and air force, said he was disappointed the new site would not be ready in time.
"Anzac Day has been established on the landing of Gallipoli and we remember persons who were at that battle in Gallipoli, but we mustn't forget all the other battles that went on around that time," he said.
�The new war memorial was going to mention all these battles and wars, but the old one just has the First World War on it.
"I�m a bit disappointed the new war memorial site isn't ready because we were all geared up to celebrate the opening of a new concept remembering soldiers of all wars."
An RBT spokesman said the new war memorial was a good project with good architect and good subcontractors and client, but its company was unable to continue to trade.
"Our problem was with other contracts," the spokesman said.
n THE City will hold an Anzac Day ceremony at the Albany Highway war memorial as it has done in the past.
