Tradition is the right word for the appointment in other ways.

The traditional diversity markers of region and language won out over more recent preoccupations with race and sex.
Here's a fun fact you probably didn't know -- Canadian judicial appointments are among the most corrupt in the entire world. That's the opinion of the human rights watchdog group Global Integrity, at least, who gave the integrity of Canada's judicial appointments a pitiful 32 out of 100 in their 2010 survey on good governance around the globe.

Intentional or not, and whatever the decision, your appointment has created a situation that can only further divide Canadians and damage the reputation of and respect for the Supreme Court you have been asked to serve.
