As a “kdp” author, I got an email about new Canadian manufacturing for kindle-direct orders (i.e. my Geometric Algebra book and various UofT physics and engineering class notes compilations.)

Here’s a fragment of that email:

“We’re excited to announce paperback manufacturing in Canada! This enables new features for KDP authors, including:

    • Faster shipping to your readers in Canada. Manufacturing in Canada enables FREE Two-Day Shipping for Prime Members.

…

Please note that, as of today, proof copies and author orders for authors in Canada will still be printed and shipped from the US.”

With the low price that I set my book prices at, paying just the US shipping for an “author proof” has been about the same as ordering a normal copy, so now there will really be no point to ordering proofs anymore.
