TWSI Step Ahead

New legislation around TWSI's now in effect 

New accessibility standards for public spaces, which includes new laws on Tactile Walking Surface Indicators (TWSI's) are now in effect. To ensure your company is compliant, contact Crozier Enterprises' TWSI Division to get an understanding of the legislation and to receive an immediate quote on TWSI's. 

TWSI is the proud supplier of Neenah Foundry cast iron detectable warning plates, which exceed the standard and are in regulatory compliance with both the AODA and the American Disability Act (ADA).

Effective January 2016, the Accessibility for Ontarians with Disabilities Act (AODA), under Part IV.1 of Reg 191/11 states that TWSI’s (also known as Detectable Warning Plates) are mandatory on all new and repaired depressed curb sidewalks in Ontario.
