I'll begin with some data on provincial government communications from our recent research. The findings are clear: communications in French were inadequate across Canada, even in those provinces and territories where linguistic obligations are more stringent. This lends support to the idea that respect for the status of French was considered less important than protecting Canadians.
I also feel that the parameters of your study are too narrow. Official languages pertain to much more than communication issues. They cut across many areas of government action. Communication problems do not reveal the whole story of the COVID-19 pandemic's impact on francophone minority communities. Their health and security also rest on the formulation of public policies and on delivering services to the public.
