Hello;

There is no adapter we carry for this. This set up may work, but I have no way of testing it.

This Bower Lens Adapter allows you to attach a Pentax screw mount lens to a Canon auto-focus camera body. You can also attach a t-mount with a Pentax screw mount adapter to Canon auto focus camera bodies.

This adapter allows a "universal screw mount" type lens (Pentax M42) to be mounted on a Pentax K-mount type body. Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions are not retained using this adapter. In this case you will need to meter in "stop-down mode" since the lens does not have the ability to have its aperture controlled by the camera body.

Hello Chuck, Mrizzle. Pardon me for butting in and someone may want to correct me but I'm not sure the bower lens adapter above will work. The bower adapter is M42 <-> 550D. mrizzle seems to have a k mount lens, not an M42 lens.

I apologise, I am not familiar enough with Canonland to be able to recommend and alternative. Something like this looks about right but I don't have the foggiest if Canon 550d is same as Canon EOS.
