It's not a case of conflict of interest. Every developer must pay for a range of studies which cover the various impacts of their proposal, including a heritage impact assessment. All of the studies argue the merits of each aspect of the proposal's design, but the City vets all of the reports to see whether the plans actually do meet their requirements and standards. It's not like the reports are all accepted, no questions asked: through the planning process the City typically seeks any changes they feel necessary to end up with a solid plan.
Sure, developers usually ask for more density than they expect they'll wind up with, and negotiations are normally quite complex covering many issues, but as part of the process the developers don't really say "approve this plan or i'll knock down heritage resource X". The typical angle is more like "since we're going to save heritage resource X, you should grant us Y density so we can afford to do it". If the whole package is acceptable to the City, they get recommended for approval by Council, if not, they can appeal to the OMB. By the time they're at the OMB, they're typically fighting about height and density issues and have usually worked out heritage preservation plans already.
