The party that called the election is the only major party that didn't have it's campaign platform ready to release. Does that seem right?
Maybe they'll release it before the debates. Maybe they won't. Really, they're just faking it at this point anyway, aren't they?

If they want to cost a platform i can see why it might take some time if your plan is to give everyone the world.
They might also just be saving announcements to be released sporadically before the election, don't want to reveal their hand all at once. They assume Canadians are stupid enough not to care too much about releasing platforms and they're right.
