As a current Canon photographer (700D owner) going mirrorless is definitely the future. Canon and Nikon have basically given up on DSLRs. (https://www.engadget.com/why-nikon-and-canon-have-given-up-on-dsl-rs-133042286.html).
However, I want to highly stress out to avoid Canon for mirrorless. The reason behind it is that Canon has been “defending” their mirrorless mount relentlessly. Meaning, that no other 3rd parties without Canon’s blessing can make lenses for the RF mount.

So unless you wanna spend big bucks on Canon approved lenses, I’d go with either Nikon, Sony or one of the other mirrorless brands.
Fun fact, Sony is actually quite permissive in the licensing of their E mount. So they will basically let everyone make lenses for the E-mount.
That will work as long as EF lenses are still available… But Canon already took some lenses out of production.
So basically, that’s gonna be a dead end path.
