Speaking to a gathering of business leaders, Moore said the federal government would provide the province with promised investment dollars whether or not voters approve the historic transit plebiscite.
A proposed $7.5-billion public transportation overhaul over 10 years would include projects such as an upgraded rapid-transit system, a new bridge and additional buses.
"We know that our cities are getting more dense and more congested," said Moore, who was in Vancouver for a meeting with members of the B.C. Business Council.
The technically non-binding plebiscite gives citizens the option of a 0.5-per-cent sales tax increase to raise money to finance the massive investment.
Ballots were mailed out in mid-March and must be submitted by May 29.
As the Yes and No sides jockey for position, residents are trying to balance traffic woes in a growing region with what some are calling a tax grab.
Proponents say the upgrades are crucial to accommodate an estimated influx of one million people to the Vancouver region over the next three decades.
Opponents have condemned TransLink, the region's transit authority, as wasting taxpayers' money.
Moore pointed to $53 billion of cross-Canada infrastructure funding that the federal government has promised over the next 10 years through the New Canada Building Plan.
He also highlighted a yearly $1-billion public transit fund targeted for big cities and announced in Tuesday's budget.
Moore said provinces are not restricted to spending the new funding exclusively on public transit and that the money can be used for infrastructure including roads, bridges and tunnels.
