You don't say where you are in Canada but I can make several suggestions. In Ontario Humber college can provide a 2 year landscape course that covers all of the basics of hardscaping and soft. Also Landscape Ontario has a Certified Landscape Technician and Certified Landscape Professional that tests for all of the things you need for landscaping. They provide courses that prepare you for these exams. You can also get an apprenticeship through Landscape Ontario that is administered through the Ontario Government

I am sure that if you look other provinces have similar programs.
