Basically, you need to get a surveyor into your apartment to itemise every non structural defect that needs to be rectified in your lot. You then need to make a claim against the developer and explain that you are aware that recent changes in the law mean they can't pass the buck to the builder.
You also need to ask your Executive Committee what they are doing about non-structural defects in the short term and structural defects in general. This is very important because if there are defects in common property that aren't attended to, it will affect the value of your unit just as much as if they defects were in your lot alone.
Don't let the EC pass the buck to the developer/insurer/builder. They represent the Owners Coprporation and the OC has an absolute legal responsibility to maintain and repair common property regardless of who ultimately foots the bill.
If you don't get anywhere in either of this areas, talk to a specialist strata lawyer about what your next options are.
