Federal, provincial and municipal government officials were on hand Tuesday to announce plans for the expansion of the Winnipeg Convention Centre, slated to cost more than $180 million.

"The expansion includes a new 340,000-square-foot addition built on a surface parking lot, immediately south of the existing 492,000-square-foot facility. The present facility will also receive significant structural and electrical upgrades," said government officials in a release.

Design images were also unveiled for the project.

Construction is slated to begin on the centre later before the end of this year.

The expansion is expected to open in late 2015.

Funding for the expansion is coming from the City of Winnipeg and provincial and federal governments, along with from property tax revenues from a commercial development and hotel adjacent to the convention centre, in addition to revenue generated by the centre itself.
