I just tested this, it is case sensitive and it doesn't ignore things after 8 characters.

I'm using TD Canada, not sure if they've maybe updated since you tried?

Strange. I tried just this morning before posting but I will update my password and try again.

edit: after updating my password it's now case sensitive, and allows special chars. As the sibling comment suggests, it looks like they have two different authentication routes and updating your password moves you onto the newer one.
