THE POP-UP flash fitted to most Canon cameras is useful, but lacks power or versatility. A proper flashgun is much more useful.

It’s an easy, wire-free method for enabling off-camera flash, which can give a more natural look to portraits and still-life shots.
Using off-camera flash will create much better lighting compared to a pop-up flash on camera
