ACCESS Workshop

problem

Inaccessible transit isn't just an inconvenience. It's a barrier to independence, opportunity, and connection.

Many planning processes fail because they lack the crucial, on-the-ground perspective of the people who use the system every day. The result? Solutions that look good on paper but create real-world problems for those who need them most. One barrier can create a domino effect in the whole system. That’s where we come in.

solution

our journey into accessibility isn't just professional—it's personal. We have family members and friends whose aspirations are daily challenged by a built environment that wasn't designed for them.

“I've seen firsthand how a missing ramp or no escalator isn't just a flaw in the concrete; it's a closed door to education, employment, and community. To spotlight best practices and highlight barriers, I have personally audited 270+ metro stations in 6 major Canadian and European cities. I walk the walk, so I can provide the insights that data alone will always miss.”
