This project was designed to integrate with Statistic Canada’s The Zone platform. In The Zone, users can create individual workspaces with Kubeflow Notebooks. To persist their work, users can attach volumes to their notebooks. These volumes are not automatically deleted when a notebook is deleted. Users are free to move them or to reuse them. As a result, over time, users tend to amass several unused volumes. These volumes sit on the cloud and result in unnecessary costs. The purpose of this project is to design an automatic system that detects these unused volumes and safely removes them, reducing unnecessary expenditure. Despite being primarily designed for Statistics Canada, this project strongly values open-source practices. The codebase is available for public use and the entire development process is documented on the issues page. The volume cleaner was designed to have as little coupling as possible so it can easily integrate into projects outside Statistics Canada. Using open-source and being open-source was an important development philosophy.

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.

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.
