What is it with so many financial firms and their ghastly, inelegant corporate branding. These cheap, shitty backlit signs are a scourge on the skyline and urban environment in general. It's not just the banks either, but I'd say that most chains have cheap, ugly branding in general. Small independent businesses with a lot less cash flow are often quite creative in their use of materials and design, so there's no excuse for all this plasticky out-of-place crap from huge companies and their much deeper pockets.
Exceptions to this are Scotia's simple, elegant stylized 'S' on Scotia Plaza, and to a lesser extent BMO's well-integrated lettering (the original 'M' was light years ahead though). CIBC's logo on CC West is an example of what TD could've done here: eschewed the clunky background box and used simple embossed lettering.
