What caliber is the rifle?
The keymod version have been very good QC wise with no outstanding issues that I know of. Wolverine I believe is the the distributor/dealer in Canada has been very supportive of the XCR if there has been any individual issues, and so has Robinson Arms (RA).
The challenge has been the 7.62 magazines, although they have gotten better, they can be a little finicky. The 30 rounders especially, I don't think you can have 30 in Canada so this may not be an issue for you.
