Is differential treatment at law discriminatory?

The courts have repeatedly indicated that not all differential treatment is discriminatory. In Andrews v. Law Society of British Columbia, 1989 CanLII 2 (SCC), [1989] 1 S.C.R. 143, at page 168, McIntyre J. writes: It is not every distinction or differentiation in treatment at law which will transgress the equality guarantees of s. 15 of the Charter. It is, of course, obvious that legislatures may - and to govern effectively - must treat different individuals and groups in different ways.
