A new consultant's report recommends city hall scrap the performing arts centre planned for London's downtown.

According to the report, project information was deemed to be incomplete in 15 different areas analyzed by Novita Interpares, including operating revenues, operating costs, functional programs, general contract costs, etc.

It says the 1,200 to 1,400 seat venue is "an outdated concept; the facility design is unresolved; the facility does not fit the site; the site is a questionable choice and the total project cost is unknown."

Novita says it also believes the true cost of the Music London project is likely significantly greater than the $40-million planned construction cost.

Music London's Murray Faulkner says he's disappointed, but, "Most of us on the Music London board kind of say the writing on the wall when this was postponed."

He also says it was never in the group's scope to provide the missing information, and the project needs to be led by the municipal government.

The report recommends the city re-focus efforts on a better design, location and plan - if a performing arts facility is a priority for the city.

It also suggests that if council wants to proceed with a different project, a community engagement program should take place in 2015, engaging all potential stakeholders - not just those with direct involvement - including future stakeholders like today's youth.

While a performing arts centre is on a long list of items in the city's new strategic plan, no dates or timelines are included.

Mayor Matt Brown says Centennial Hall has only a five to 10 year lifespan remaining, but won't say if he'd push for a new facility right away.

"There is an opportunity cost here...by investing in a project like this we may not be able to make investments in other projects, that's why we need to get our priorities right."

The report will be discussed by council at a meeting on Monday.
