Accurate accounts must be presented to an AGM. If they are accurate, they will show the debt. If they are not presented clearly, then you could interpret for the benefit of others or ask the treasurer to explain.
Since you are a member of the committee, you share the responsibility to ensure that proper meeting notice is given and accurate accounts are presented.
As for specific works (eg. the fence repair), why can’t the committee include funding for these as part of the proposed budget for the coming year? The OC is obliged to maintain its common property so it should not really be up for debate about whether to do it.
Parking issues are a different matter. One approach (since I don’t know the detail) would be to give notice to the chair that you wish to discuss parking under the “Other Business” item. The chair should give priority to notified matters over not-notified matters. If you don’t have a specific motion about parking on the agenda as notified to owners, then the meeting can’t make a formal resolution. However, the minutes could record that parking was discussed and there was ‘some specified general consensus about how parking should operate’ or that ‘opinion was about evenly divided between certain options’ or that ‘the incoming committee was asked to prepare a recommendation taking into account the various views heard at the meeting’ or whatever.
