From what I can see, the CZ flight LHR-CAN can be booked in conjunction with DL if you are connecting from the US, but only as a CZ flight (not as a codeshare with any of those 3 carriers).
The CZ flight CDG-CAN can be booked as AF codeshare, and their AMS-CAN can be booked as a KL codeshare, but neither as DL. AF also operates a CDG-CAN flight.
I know that doesn't answer your question about websites, but I don't know of one offhand.
