A Flat Pack refers to the packaging. This is a flat cardboard envelope rather than a retail box. Yes this will protect your laptop.
Flat rate shipping pricing varies by the size of the container one would ship the an item in. The price ranges from $5.05 for a small envelope to $16.85 for a large box.
The rate for USPS flat rate envelopes through Priority Mail International is $19.95 to Canada. Depending on how much weight you are shipping, it may be significantly cheaper to ship through standard mail.
It all depends on the envelope size. A standard flat envelope is about $1.00 while a larger flat envelope is about $1.24. I had the same question and found my answer here: http://postcalc.usps.gov/
