In the statutory questions section, there are two fairly similar questions:
I once applied to UK visa, and got refused. Shall I answer yes to both?4: Has XYZ you been refused refugee status, or an immigrant or permanent resident visa (including a Certificat de sélection du Québec (CSQ) or application to the Provincial nominee Program) or visitor or temporary resident visa, to Canada or any other country?
5: Has XYZ ever been refused a visa or permit, denied entry or ordered to leave Canada or any other country?
