As the Utility Belt reported last week, Google (GOOG) Finance Canada was scheduled to launch today after a false start. The localized version of Google Finance is indeed available, as signaled in a post by Google engineer (and Canadian) Dion Loy.
Quoting from the post:
Google faces plenty of competition in the financial data and information business. The clear leader is Yahoo (YHOO) Finance, which provides more financial data and reference materials. Yahoo already has a localized Canadian site.
