The committee was created by the Metro Vancouver Mayors' Council as an assurance to taxpayers the money will be properly spent.
Other than that, very little is known about the exact role of the committee — even to Pattison himself.
"I have no information about it, except that they asked me if I would help oversee the funds if the yes vote wins and I said I would be happy to do that," Pattison said.
The Early Edition spoke to chair of the Metro Vancouver Board of directors and Port Coquitlam Mayor Greg Moore for more clarity on what the committee will actually do.
Take the poll: Do you support this proposed tax hike?
1. A yearly audit
Moore said the question on the ballot will already include the promise of a yearly audit — done outside of TransLink.
"We really heard loud and clear that people wanted more assurance that this was going to occur," he said.
"We couldn't think of a better person to ask to come forward to oversee that to make sure that that money being collected is going to deliver the plan."
2. Mirror the success of other referendums
Moore said the idea of an advisory committee was borrowed from the aftermath of similar transit referendums to the south, including in Los Angeles.
"When we went and looked at referendums down in the states, one of the successful things they had was an oversight committee afterwards," he said.
3. Reassure the public that money is being properly spent
Moore didn't say whether the new committee would have any legislative or statutory authority, but said both the Mayors' Council and TransLink board will listen to the advice of the new committee.
"I think this just gives it that extra assurance that it's not government, it's not the TransLink board — it's someone that we've looked to before that will oversee that."
