The city has given the OK to a community group looking to bring the 2030 Commonwealth Games to Hamilton, but it will do a risk assessment to make sure it's not on the hook for unforeseen costs.

Hamilton city council voted Wednesday to order an independent peer review of whatever financial model Hamilton 150 will use to make a pitch for the games. It also wants its staff to look at the proposal and identify any risks, including cost overruns.

"The peer review is to make sure we're comfortable with their financial model," said Coun. Brad Clark of Ward 9. "It's not our proposal, it's theirs."

Otherwise, city council is supporting Hamilton 100, a group advocating that the city play host to the games 11 years from now. The group's plan includes three new multi-sport complexes, more affordable housing, and upgrades to facilities using what it hopes is money from the provincial and federal governments.

Hamilton 100 outlined its vision earlier this month with a document that doesn't include dollar figures. The 2030 games are an important anniversary, the group says, because Hamilton hosted the first version of the games in 1930.

Each Canadian city interested in hosting the games will have to submit Part 1 of their plans, which includes vision and a financial plan, to Commonwealth Games Canada by Nov. 22.

The cost to host the games varies. Glasgow, Scotland spent around $300 million Canadian dollars when it hosted in 2014. Preliminary estimates for the 2018 Commonwealth Games in Australia indicate a price tag of over $1.8 billion.

The cost to hold the 2022 games in Birmingham, England is expected to hit about $1.5 billion.

Brian MacPherson, CEO of Commonwealth Games Canada previously told Hamilton city councillors that the total cost can run around $1.5 billion.
