You're just not going to give up, are you. I would suggest you visit the modelling site called
missing-lynx. Lots of info on Canadian Centurions. I also learned a lot from Maple Leaf Up, which is now defunct. Might be available on the wayback machine. Look online for links to Jason Bobrowich and Centurions. He's done a lot of modeling work which includes the paint schemes. FInally, see if you can find a copy of this two-disc CD on the Canadian Centurion. I haven't seen it myself, but it was made by TrackJam Models, 4 gbs of pdf's and jpeg's.
PS: The headlights from the 3D model might be okay for a Canadian Mk11, but not the fuel tank or the IR light.
