I think our worst is the logo (and motto, and built form) for the suburban Town of Conception Bay South.
One of the local rugby clubs, the St. John's Swilers (that's the term for someone who hunts seals) is probably the only thing with our nationalist flag slapped on it that I dislike. It's just too detailed with the Matthew, a seal, and a pitcher plant.
Newfoundland Television's logo is brutal.
Jumping Bean (local coffee house chain) has a logo I love. Not sure why - but it's so cute and inviting passing their location.
And another I really love is Fog Off, a clothing line/store on Water Street.
