Make sure you're on the website (not mobile), go to My Trips, and click on Manage Flight.
From there you can click on Print itinerary, and then select "Include your detailed fare summary", but do not select "Include travel information....".
This will give you the most compact version of your booking receipt that still breaks out all of the different taxes and fees, so that your expense report people will be happy (source - i'm the expense report people for my office).
If you've already flown, just go to the AC website and select Contact Us, then Post Travel, and then Receipt Requests.
Yup, sometimes do that but even this short version can easily extend to three pages... and it can look awkward if you do this after requesting an upgrade as that shows up on the receipt as well.
