Yes. It can still be useful to understand how short-term entry fits into your broader plans, especially if you are also considering future study, work, or permanent residence.
That depends on your purpose, your timing, and your wider plans. It should be chosen because it fits the situation, not because it looks simple on the surface.
Not by itself. Visitor entry is temporary and should not be confused with long-term immigration pathways. In some situations it may be part of a wider strategy, but it is not the same thing.
Sometimes, but it depends on the circumstances. Visitor entry should always be approached carefully and honestly, especially if there is also a longer-term interest in Canada.
