It wouldn't surprise me if restrictions came into play for the summer if anything was to happen. Its seems best to go ahead with the day since you have gotten everything booked though the numbers may be less than what you have now. The chances of the full guest list being present is unlikely if you have a reception/anniversary party after the wedding itself. I do hope its safe for the summer and you get to enjoy your day.
Hard to say. With two summers in hindsight, July seems to be a safe bet in terms of low covid numbers. At the same time, higher gathering counts of more than 100 people were only allowed at staffed venues, not private gatherings. You may have to split your list into an A and B list if that's the case.
Don't forget that private gatherings also include every vendor you hire into the count.
My fiance and I are August 7 2022 in Kelowna BC. I'm hoping that by the time summer roles around we'll be able to have our wedding with limited restrictions just like this past summer. Crossing our fingers though. We've already postponed twice
