Some parts of these headers look faked to me, in particular, the bottom most Received is definitely faked, and probably also the bottom most Received-SPF and Authentication-Results.

The current SPF records for telus.com don't seem to allow sending by 69.64.35.11.

Did someone figure out how to trick gmail into accepting bogus headers indicating the SPF passed?

Also, the timestamps on the received headers differ by a lot. This one:

    Received: from gown.ShoppingBrew.com (ec2-13-58-85-245.us-east-2.compute.amazonaws.com. )
            by mx.google.com with ESMTP id n59-v6si5794010qtd.116.2018.04.20.00.37.14
            for <my.email.fake@gmail.com>;
            Fri, 20 Apr 2018 00:37:14 -0700 (PDT)

appears to be identical (except for the email address) for the two sample sets of headers in the thread.
