Transit and Infrastructure are foundational to the livability, sustainability, and economic competitiveness of cities. Efficient and accessible transit systems not only facilitate mobility but also foster social inclusion, reduce greenhouse gas emissions, and alleviate traffic congestion making cities more livable. By delving into transit and infrastructure issues, CUI addresses critical urban challenges such as equitable access to transportation, infrastructure maintenance and expansion, and the integration of emerging technologies. Moreover, transit-oriented development represents a multifaceted approach that leverages transit investments to catalyze vibrant, walkable communities, spur economic development, and enhance quality of life. CityTalk’s engagement with transit and infrastructure extends beyond conventional transportation modes to encompass broader infrastructure systems, including water, energy, and telecommunications networks, which are essential for sustaining urban growth resilience. CUI is making the case that Main Streets are themselves critical infrastructure. Our cross-Canada conversations amplify work in the realms of research, policy, advocacy, and knowledge exchange, and generates opportunities for the advancement of evidence-based policies, planning frameworks, and investment strategies that promote sustainable and equitable transit and infrastructure solutions. By bringing individuals working on transportation and infrastructure together, CUI ensures that these massive investments and policy directions align with broader goals of social equity, environmental stewardship, and economic prosperity.
