Exploring User-Uptake of Digital Contact Tracing Apps - A Practitioner Guide - Special Edition/Module 10 - Case Study: Canada
Bibliographic record
Abstract
This module aims to explore Digital Contact Tracing (D-CT) developed and implemented in Canada for the COVID-19 response. Focus is on the country’s D-CT app, COVID Alert, and understanding user-uptake. The case study begins with a brief overview of the country’s overall response to COVID-19 and the impact of the virus on the country. Following, we explain Canada’s app by describing, how it emerged, how it is designed and functions, how users engage with the app across the whole user-engagement process, and what user-uptake looks like in the country. The next section examines all eight factors identified in the other case studies (1) Perceptions of Data Collection & Management; 2) Sense of Community; and 3) Communications & Misinformation; 4) Accessibility & Inclusion; 5) Trust in Public/Private Institutions; 6) Policy & Governance; 7) Response Infrastructure; and 8) Digital Capability) plus a ninth factor specific to Canada — Provincial & Territorial Support.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
