You may want to link data from two or more databases across PHSA. This requires data from one database to be sent to another for linking to be carried out. Depending on the governance of the database, this may require one data steward to sign a data sharing agreement with the other to outline how the data will be transferred, linked and returned/destroyed.
While you may not be directly involved in drafting this agreement, it is important to connect with these data custodians early on in the process since they will need to determine how best to fulfill your data access request and what supporting information you will be required to provide. Be aware that some data stewards have other requirements, including privacy impact assessments, which may add to your timeline before the data are received.
If you are an External Researcher (i.e. not Affiliated with PHSA), you may be asked to sign additional agreements outlining that you will comply with applicable laws and PHSA policies pertaining to the data disclosure. PHSA-Affiliated Researchers and PHSA employees are bound to applicable laws and PHSA policies through affiliation agreements, employment/consulting contracts, and the annual renewal of PHSA privacy and confidentiality training.
