Certainly no issue with LR, 10.6.7 and Canon Pro9000 for me.
Using LR3 and under OS 10.6.7 you don't have to turn colour management off. It's done automatically for Canon printers as soon as you choose the printer profile in LR's Print Module. Colorsync is automatically chosen - every other option is greyed out in the printer driver. As long as you have chosen the correct media setting in the driver, and assuming the Canon test prints show heads all clear and aligned, everything should be OK.
I'm assuming you're using a Canon paper and the appropriate profile. Third party papers are another thing, as the correct media setting can be a lottery and, in my experience, the only way to get good profiles is to build them yourself.
Have you looked at the prints in daylight? - the issue is not to do with your local lighting?
Good luck
