Core accessibility features include a clear floor area of 1500 mm × 1500 mm at the rider zone (CSA B651 7.5), a contrast strip at the door opening with 70% LRV contrast against the wall colour, tactile warning surface indicators (TWSI) at the boarding edge per CSA B651-18 6.1.4, and bench surfaces between 430 mm and 480 mm above grade with front and rear armrests for sit-to-stand assistance. Approach gradients are designed for 1:20 maximum running slope and 1:50 cross-slope to accommodate manual and power wheelchairs.
Visual accessibility is addressed with tactile lettering on route signage (raised characters 0.8–1.5 mm, CNIB-recommended sans-serif font), Braille route numbers (Grade 2 / UEB), and luminance-contrast pictograms with a minimum 3:1 contrast ratio against the panel. Lighting is 150 lux at the bench with anti-glare diffusers; a motion-activated audio announcer is available for vision-impaired riders. Optional hearing-loop induction system (T-coil compatible) integrates with real-time arrival audio.
The compliance pack includes the AODA conformance letter, CSA B651-18 design checklist, dimensional accessibility drawings, and the photometric/contrast lab report — everything procurement teams need to clear an accessibility-board review. Lead time 8–12 weeks. Uplift over the standard shelter is $500–$1,200 depending on the visual-accessibility options selected.
Documentation, audits, and warranty
Every accessible shelter ships with a compliance binder containing the AODA conformance letter (or provincial equivalent), CSA B651-18 design checklist with each clause cross-referenced to the as-built drawings, photometric and contrast lab report, tactile surface manufacturer certifications, and the stamped accessibility-board review pack. This is the same documentation format used by the Ontario Public Service Accessibility Office, the Office québécois de la personne handicapée, and the Accessibility Directorate of BC for their own accessibility audits — most procurement teams can drop our binder straight into their submission with no edits. Warranty is 10 years on the structure, 5 years on tactile surfaces and Braille panels, 3 years on the audio announcer, 5 years on the hearing-loop system. Annual accessibility re-audit (visual and dimensional) is included in maintenance contracts at $400–$700 per shelter per year.
> Key Takeaway: Climate-rated, AODA-compliant, and stamped-engineered for Canadian transit deployment — full procurement documentation included.
