For Creating a Respectful Workplace, I do have some statistics here. It's one of our most popular courses. We had 64 offerings in 2009-10; 24 in 2010-11; and 16 in 2011-12. The other courses, as you point out, are offered less frequently. Sometimes we do them by MOU with departments.
Typically, we have at least one offering per year in each of the official languages.
