At least the Canucks logos don't just lie to try to justify their team name like Ottawa.
The Senators don't have an actual Roman senator as their logo. It's an optione (it's unlikely that the designer actually knew the difference between an optione and a centurion). Senatorial rank was a societal rank and political office, but not a military office. You had to be of senatorial rank to be an officer in Rome, but that didn't make you an actual senator.
Also, can we talk about the helmet for a second - Roman military helmets didn't have visors. The "Senator" is wearing an adult version of this, with the addition of Corinthian-style cheek protectors. It's a historical nightmare.
An actual acting senator in the Roman Senate would be an old man in a toga, possibly with a scroll. If we're talking logo accuracy, something that looks like this guy would be more appropriate:
Also, notice the difference between Roman military uniform and Roman senate dress, easily illustrated here. Guess who the senator is (hint: he's in the front.)
