3–5 years of audit & assurance experience in public practice

Solid technical knowledge of GAAP, audit / review procedures, and tax compliance

Nestled in the heart of Niagara, you’re just minutes from world-class wineries, the U.S. border, and the shores of Lake Ontario. The city boasts abundant green spaces, waterfront trails, and a growing local economy with opportunities across multiple sectors.

And when you crave the energy of the big city, Toronto is just a quick drive or GO Train ride away — giving you access to it all, without living in the daily grind.
