Web components and packages for building Ontario government digital services.

This Directive outlines requirements for ministries and provincial agencies on listing all data inventories, publishing open data, and preparing information systems to support ongoing open data requirements. The open data initiative supports government efficiency, effectiveness and innovation. Faster and easier access to government data through a one-window data portal facilitates evidence-based policy, informs service delivery and promotes greater transparency and accountability. The open data initiative also supports public engagement and participation by allowing Ontarians to develop their own analysis, insights, and digital products. To support this implementation of the directive, an Open Data Guidebook is available as a tool and resource to Ontario ministries and provincial agencies. The Open Data Directive is a Management Board of Cabinet Directive, issued under the Management Board of Cabinet Act.

GC Design System Tokens are the smallest building blocks of the design system. They represent design decisions for basic elements like colour, typography, and spacing, creating a curated set of options that we base our designs on. Tokens replace hard-coded values with variables that can be reused throughout the entire code base which makes it easier to maintain and update any code. Our tokens help us create a consistent visual experience that meets the Government of Canada requirements. They also improve communication between design and development by establishing a shared language.

CSS Shortcuts is a CSS utility framework built to match GC Design System (GCDS) styles and Canada.ca standards. It provides predefined CSS utility classes that apply core design elements, like colours, spacing, and typography, to your HTML. The classes align with our GCDS design tokens for consistency and ease of use.
