Not about traffic tickets
per se, but about language rights in the courts in all provinces and territories.
The study itself was methodologically questionable (very small numbers of respondents in many cases, e.g.), but it presents the issues as they're perceived by members of official language minority groups.
There is no constitutional guarantee of the provision of services in both official languages by most provincial governments (or municipalities). However, in this case, the ticket violated the city charter itself, and so was presumably not regarded as a valid ticket.
The Franco-Manitoban community has struggled against heavy odds to survive and develop as a community, and for its members to have opportunities to succeed as individuals without having to abandon their culture. Sometimes the issues are more basic and immediately crucial: the need of francophones to be able to access health care services in their own language, for instance ... and this basic need is the motor behind claims for governance of institutions like hospitals, and access to advanced training in French for francophones who will then be available to serve the francophone community.
Ottawa ... well, the question of whether Ottawa, as a municipality, should be officially bilingual, has been a political hot potato for years, and I don't think the matter is settled yet.
