Becoming an instructor in Canada

You will need to have held a full UK/EU driving licence for at least 4 years out of the last 6 years. What is a UK/ED licence? I use to be a driving instructor for driving semi trucks and have had a class A licence with doubles/triples, tankers, hazmat and motorcycle for 24 years, does that qualify for anything? And are there any driving course in CA that you may go to like a trade school that will put you through all the requirements you need to become a instructor? Kind of like a truck driving school, only an instructor course, and if so where would you suggest I look? And how long do the classes generally take if they have them?
