I have done the same with a Miles&More reward flight booked through LH and operated by AC. What you need to do is:
- Contact Lufthansa and ask for the Air Canada booking reference (PNR). This will be a different 6 letter/digit code to the one used by LH
- Use this booking reference to manage your booking on the AC website
- Also, if you ring up AC with this code, they will let you book seats in advance for a fee, but they don't let you do this on the website if the booking was not made with them
