If you want to be a certified teacher, you will have to have a university degree. But perhaps, for you, a year working might be a good idea. Some people do this to help pay for university, & also to give themselves time to figure out what they really want to do.

In the U.S., the first two years of classes are pretty much the core curriculum (classes required of everyone regardless of one's major). If Canadian unis follow this pattern too, then you don't have to know exactly what you will get your degree in when you start out. That's something to consider. If you think you eventually want a degree & you can mentally settle into studying, then go ahead & go to university. Otherwise, you may need some time off from school to consider just what your goals are.

In the U.S., studying a trade almost never leads to a degree, so I don't think we Americans can answer the question as you asked it. Here, even if you worked/learned a trade & received credit for "life experiences," you'd still need the classes in history, composition, political science, economics, literature, etc. So, we're back to if you want the degree, go to university.

Best to you in making your decision.
