Secured pdf says signing is allowed, but I can't seem to do it

The pdf in question is from the government of Canada. Here is the a link to the file, and here is the website.

When I open the file in adobe acrobat, I can edit all the forms, but can't add a signature at the bottom (the "sign" option is greyed out. I check the properties of the document, and it says signature is allowed. How do I sign it?

I have both Acrobate 11 and Reader 11 installed. I have tried both, but neither will let me sign the document.

Here's how I solved it:

Open the pdf in chrome, print it to pdf. You can now edit it.
