Toronto Mayor David Miller and several city councillors held an open house at Union Station on Wednesday to seek public input on revitalizing the country's busiest transit hub.

Display panels showcased some of the proposed changes for the city-owned heritage building.

The main suggested upgrades are to pedestrian areas and connections to the city's PATH (underground walkway) and GO Transit, Via Rail and TTC systems.

The design options also aim to open up access to the city's downtown and waterfront.

Officials were looking for suggestions on how to modernize and improve the historical landmark. Specific commuter-friendly design options were also sought.

Residents were encouraged to speak with staff and fill out a questionnaire with their ideas.

"This is a great facility that's languished for 50 years, and we have the chance now not only to bring it back to its former glory, (but) to make it a destination were people want to go, where people choose to go, not just have to go," Miller said.

"We've developed a vision for the station that sees the city maintaining ownership of its crown jewel."

The plans also call for a retail concourse, which the mayor said would generate revenue for the city.

"This project has been undertaken on the premise that there will be significant private investment in the retail in this building, which will allow for a sustainable financial model over time," Miller said.

The fresh push for a Union Station makeover follows the $150-million renovation plan that fell apart last year.

The city had a private-sector partner with Union Pearson Group, but the deal was scrapped just weeks before the two sides were to wrap up the last details of the agreement. There were disagreements over a number of issues, including a lease agreement with tenants GO Transit and Via Rail.

Taxpayers will now fund the project, but city officials haven't yet announced the final cost. That figure will be presented to the executive council in a few weeks.

The city has set aside $85 million for the plan in this year's capital budget.

While Coun. Doug Holyday says the Union Station facelift is a priority, he said it's unfortunate public dollars are paying for it.

"I think it could have been done in a way without the taxpayers having to contribute, but we had our chance and doing that and blew it," Holyday said. "Now we have to do our best with it."

Those who had a look at the new plans seemed to be on board.

"I think it's time that we really make it a showcase," one resident said.
