Got the notice to take the oath today! I can update that my spouse and I both passed the citizenship test on March 13, we were approved at end of same-day interview, and told we'd be contacted about a date for the oath. Notification came today, 4/24/2019, for oath in Mississauga, Ontario (100 miles from our home, sigh) on 5/10/2019. Sadly, it's the only day of the coming months that I have to be in Montreal, so I must write them to ask for a new date. I hope the next one is not also a conflict. I wish they'd let us apply for a range of days or a range of weeks! AH, well.
