I was asked to send my passport to Ottawa for a visa stamp which I did, but I made a mistake in the address by omitting the “e application “ part of the address. Although I correctly put every other part of the address including postal code and P.O. Box I’m not sure if the omission will be an issue. Canada post app says it’s been delivered and signed for, Please I was wondering if anyone knows how I can be sure it’s the right place I sent it to?
