My Dev circle on Google+ has alerted me, just before the end of the early bird deadline, to the existence of jQueryTO - Toronto's jQuery Conference ! It boasts such speakers as Dave Methvin (jQuery Foundation President), Paul Irish (of Google Chrome), Jen Fong-Adwent (of Mozilla) among many more!

Topics don't seem to be limited to jQuery, and will include talks on AngularJS and possibly other frameworks.
See you there!
