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.

Digital Journeys is an open-source project or repository maintained by Government of British Columbia in Canada.

Aries Verifiable Credentials Registry (VCR), part of the Hyperledger Aries family of Digital Trust technologies, provides a searchable public directory based on Verifiable Credentials (VCs). It was historically known as both OrgBook (which is actually a deployment of Aries VCR) and Indy Catalyst. Aries VCR is actively developed by the British Columbia Government’s Digital Trust Team in Canada, and the most well-known live example is OrgBook BC. In an instance of Aries VCR, credentials can be issued from a variety of authorities about subjects in the instance. A core set of credentials are issued by an authority responsible for “creating” the subject. Other credentials can then be issued against the subject of these core credentials. All credentials are stored in a secure digital wallet and accessed via its website or the public API. This means an instance of Aries VCR can be an authoritative public registry of any referenceable information.

Digital wallet solution comprised of plugins layered on top of OpenWallet Foundation ACA-Py, which streamlines the process of sending and receiving digital credentials for governments and organizations.

A standards-based digital preservation system for maintaining long-term access to digital records.

A digital audio workstation for recording, editing, mixing, and mastering audio. NOTE: Ardour is free and open source for its source code only. Precompiled versions of the application for various operating systems are available for a fee. Per the developer's website: If you want the convenience of using our ready-to-run version and/or for support from Ardour developers and experienced users, we ask that you pay something for this. If you don't want to pay for a ready-to-run version, then you'll need to get the source code and build it yourself. We do not provide assistance with this process and particularly on Windows and macOS this can be challenging and take a long time. Also, for Windows, there are no instructions.
