A planning study for graduate study in the mathematical sciences in Ontario undertaken in 1976-77 resulted in some general and specific observations about the Ontario universities. In general, graduate work in the mathematical sciences is of good quality, and most fields of mathematics are completely covered in one or another university; some fields are indentified for further development. Enrollment projections are considered to be in balance with the number of graduates and job opportunities, although enrollment-to-graduation ratios are low for doctoral students. It is recommended that the universities carefully watch enrollment/graduation data and the employment market for changes. It is also felt that part-time study be made available at the master's level when feasible. Specific recommendations are made for the individual universities' program development efforts. (MSE)
