The Government of Canada Open Government Portal (the Portal), is a data housing and linking system, developed to allow the public to find and make use of government data and information. The Portal is in need of a redesign to improve overall user satisfaction and understanding of provided data. Additionally, in the Portal's lifetime, data visualization has become an important focus area. Data visualizations allow the reader to strengthen their understanding in a subject area, while improving their understanding of data analysis in parallel. Data visualizations communicate results differently than raw data text-based tables. In doing so, relationships are presented that may be otherwise unclear in raw data, including immediate results such as outliers in the data. By performing a usability analysis on the the Portal, we created an understanding surrounding the overall success of meeting the primary goal of the Portal: to provide an easy and accessible way for the public to access, view and obtain federal government data. Our usability analysis involved a cognitive walkthrough, along with a user study, to understand how to best present data to Canadians. Results confirmed that the Portal was in need of improvement regarding data presentation. We determined many of the pitfalls within the design of the Portal to be related to language and copy used, along with structural design and placement of features. It is our belief that future research on language used within the Portal, along with the development of a design style guide, would result in enhanced engagement and overall user satisfaction when presenting data to Canadians.
