I copied some cells from a previous sheet. I think things are mostly correct now.
Im watching ceremonies in nova scotia. Two ceremonies in Halifax and one in Dartmouth and another one in Capbreton since September 21

Im not sure if they will have another ceremony in Halifax in December. They seem to have a ceremony every 30 - 40 days . the current one is in November 20. the next one should be the end of December, or in January (if they stop ceremonies in the holiday season) .
Im quite sure we will receive some notification in the next few weeks, before the end of the year.
I hop you will get the invite very soon. May be we can be invited to one ceremony
