UNIQUE PROJECT HURDLES
The Portlands area is part of Toronto’s large waterfront revitalization project and is home to rowing, windsurfing, and sailing clubs as well as many walking, biking and rollerblading trails. To protect the environment of this vital area, Portlands has been carefully designed to be a ‘green industry’. INNOVA/Higgott-Kane custom-engineered the exhaust silencing measures to meet the stringent noise levels required to comply with this standard and guaranteed performance results.
