How have the courts in the United States and Canada treated the issue of age discrimination in the hiring of bus drivers?

Again, on this matter, United States' cases have influenced Canadian Boards of Inquiry: for eg. Hodgson v. Greyhound Bus Lines Inc. 499 F. 2d. 859, (1974). There, the employer refused to hire bus drivers who were older than 35 yrs. Considering the nature of the job, Swygert C.J. stated: [A] public transportation carrier, such as Greyhound, entrusted with the lives and well-being of passengers, must continually strive to employ the most highly qualified persons available for the position of inter-city bus driver for the paramount goal of a bus driver is safety. Due to such compelling concerns for safety, it is not necessary that Greyhound show that all or substantially all bus driver applicants over forty could not perform safely ... Greyhound need only demonstrate, however, a minimal increase in risk of harm for it is enough to show that elimination of the hiring policy might jeopardize the life of one more person than might otherwise occur under the present hiring practice.
