The FirstOntario PAC is a 95,000 square foot cultural complex comprised
of four state-of-the-art performance venues that host a signature
presentation of international and local performing artists. Designed by
Diamond Schmitt Architects, the PAC plays a vital role in the
renaissance of downtown St. Catharines, serving as the catalyst in
thoroughly modernizing the area and reinforcing the brilliance of
Niagara Region's diverse cultural cluster.

Four venues make up the centre: Partridge Hall, Robertson Theatre, Cairns Recital Hall and the Film House.
