When I entered law school, each year the most powerful law firm in Montreal would obtain from McGill Law School the names of the ten students with the highest grades in their first year of law school and write to them to offer them summer jobs. I received such a letter when I completed my first year of law school in 1976.
Had I gone to law school a few years earlier, I would not have received that letter, because the firm extending it had made it a practice to exclude Jews from the program.
