London is a key electoral constituency the Liberals lost with the collapse of the Liberal vote in Southwestern Ontario during the 2011 federal election.
Trudeau will take questions from reporters at 12 p.m. ET. CBCNews.ca is carrying his remarks live.
On Tuesday, Trudeau attacked the ruling Conservatives' economic record, saying the finance minister's decision last week to postpone the federal budget until April at least is proof the government has no "plan B" to deal with falling oil prices.
Trudeau also reiterated his promise to reverse the government's income splitting plan, a measure Trudeau said would only benefit the rich.
The experts that will speak to Liberal MPs on the economy and local issues are:
- Kadie Ward, founder of Build Strong Cities.
- Jayson Myers, president of Canadian Manufacturers and Exporters.
- Matt Brown, mayor of London, Ont.
- Janet Vanderheyden, mayor of nearby Strathroy, Ont.
- Gerry McNamara, mayor of Tecumseh and president of the Association of Municipalities of Ontario.
- Bob Bratina, former Hamilton mayor and a current Liberal party candidate.
Party officials noted the guest speakers are "independent, non-partisan" experts, although Moffat also serves on the Liberals' council of advisers on the economy.
