On May 4, 2023, the Government of Canada published updated instructions for the Safe Third Country Agreement. Effective March 25, 2023, the Safe Third Country Agreement (STCA) has been extended to cover the entire land border through the implementation of the Additional Protocol (AP). The AP, together with corresponding regulatory amendments, expands the application of the STCA to include individuals who submit an asylum claim when entering Canada between ports of entry, as well as those who submit a refugee claim inland following an irregular entry.
