The 1980-81 and 1979-80 enrollment patterns of foreign students in Canadian universities are compared. The total number of foreign students increased rapidly during the early 1970s, peaked in 1976-77, and leveled off or declined in the following three years. Provincial patterns, however, did not conform to this national trend. Universities in Quebec and the Prairies experienced a decline that continued in 1980-81, while gains in Ontario occurred, so that the latter province now accounts for 47 percent of the foreign students in Canada's universities. Numbers fell both in provinces that had and had not imposed differential fees. Asian students (except from Hong Kong) accounted for most of the increase in Ontario, and to some extent in British Columbia. Whereas Americans comprised almost 25 percent of all foreign university students during the middle 1970s, this proportion had fallen to 13 percent in 1980-81, and the absolute number decreased. Another feature of the present enrollment pattern is that the number of students from a selected 25 of the least developed countries has declined. A breakdown by geographic origin shows that most Europeans, Americans, and those from India and Pakistan are studying at the graduate level, whereas foreign students from many developing countries and from Hong Kong and Malaysia tend to be undergraduates. Foreign students are particularly numerous at the doctoral level, accounting for one of four full-time students. Their numbers have risen gradually since 1976-77, in contrast to the leveling off or decline of foreign students among undergraduates. The rising proportion of foreign students at the Ph.D. level is a result not only of increased enrollment but also of a simultaneous decline in the full-time enrollment of Canadians and permanent residents.
