Breaking Barriers: The Urgent Need for Accessible Living Spaces in Canada

In Canada, 6.2 million people (22% of the population) live with a disability, and this number is rising due to an aging population. Despite this, many homes were built before accessibility standards existed, making modifications costly and complex. People with disabilities face higher risks of social isolation due to inaccessible housing, yet accessibility upgrades can add as little as 1% to construction costs.

The real estate and construction industries lack standardized guidance, leaving homebuyers, builders, and renters struggling to assess and implement accessibility improvements. To address this gap, the federal government has pledged $30 billion over 10 years to improve housing accessibility—but there’s still a critical need for easy, AI-powered tools to make homes truly inclusive.

In this Case Study you will find the following sections:
