We do not have figures to give you on that point, unfortunately.
However, I really do want to stress the fact that the convergence toward English is happening in a lot of countries and the difficulties in publishing in a language other than English do not just exist in Canada. There are virtually no more journals published in Italian, in Spanish, in German or in Japanese. The exception is China, because a lot more scientific research is being done there than 25 years ago. Otherwise, a decline can be seen in all languages.
As I said in my opening remarks, what we are calling for is really based on the Helsinki Initiative, which seeks to promote multilingualism in research.
