Shield Plans Comparison on MOH website
To compare Shield Plans at a glance, check out this neat page on MOH website.
Policy wordings of various integrated Shield plans by the approved insurers and a comparison table can be downloaded for reference.
I particular find the policy wording information a good resource, since many clients and friends tend to ask similar questions whose answers can be referred from such material.
Word of caution is that accuracy of info is based on date of last update. Therefore, please use this purely as a general reference guide.
