Can you suggest some books to read on how to become a Canadian diplomat?

Some information re qualifications:

How to qualify: Like most civil services positions, an undergraduate degree—in anything from economics or politics to health sciences and engineering—is a bare minimum requirement. At the federal level it helps (and is often essential) to be bilingual. And for diplomats, a third or even fourth language can help. To move up the ladder, a graduate degree might be necessary. For top-level government program officers, meanwhile, a PhD isn’t required, but it’s not unusual either.

Probably our most famous diplomat was Ken Taylor who died last year.

One of my high school buddies worked for Flora McDonald at the time of the Iranian Hostage Crisis and was involved in getting the passports to Tehran.

There are good links at the wikipedia link to additional reading about Ken

He and his wife Michele Landsberg have written quite a bit, so look some of their work up.
