What is Open Data?

Open Data is data that can be freely used, reused and distributed by anyone without restrictions from copyright, patents or other mechanisms of control.

Why Open Data?

Open Data is an important component of accountable and transparent government. It creates community engagement opportunities and empowers community members to establish civic innovations using City data. It improves service delivery, creating efficiencies by removing data request processes and making data readily available.
