Microsoft has forgotten the Great White North's love for WP7, WPCentral has posted a link to something called the Developer Movement.
The all too weird part of this is that it is for us Canadians developers only. First 200 to sign up gets their AppHub fee waived, only if you are not already registered as on AppHub. You can still join the movement for a chance at the other prizes (provided that you submit a quality app - whatever that means) up until May 20, 2012
More information on the website but here are some information:

Good luck! and Happy Coding!
