I've just gotten approved for permanent residence (found out on My CIC and am waiting for my COPR letter to arrive). Quick question about the expiry date: it says in the letter that I must arrive in Canada on or before 04/05/2018 -- just checking that this is day-month-year format?? My medical exam was on 20 April 2017 so I expected it to be a year from that date but obviously this date is either two weeks before or two weeks after, really hoping it means 4 May and not 5 April!
