I've read three-year-old reviews of the 70D, the Rebel's more advanced cousin, and it does have the electronic level feature but does the T5i have that feature? Just out of couriosity, does the T6i & T6s have the electronic level feature as well? My younger brother just got I believe the T6i after Christmas and he asked me and I wasn't sure.
I'm not certain if your camera has it BUT... on cameras that do have it (my 5D II does not, but my 60Da and 5D III both do) you press the "info" button (on some models it's labeled "Disp" instead of "Info") a few times and this cycles through several things the LCD screen can display. If your camera supports the level then you'll see it pop up.
