We're invited to a family wedding in September 2021 in a location in Washington state near the Canadian border. We have longtime friends on the Canadian side. Our original plan (before Covid came and the wedding was postponed by more than a year) was to attend the wedding and visit our Canadian friends. We live on the east coast of the USA so this would be a major trip for us, and we're reluctant to do it unless we can combine the Canada portion with the wedding.
Currently the US-Canada border is closed to nonessential travel until at least May 21. I know there is no way of telling what the situation will be by September, but just wanted to toss this out for discussion.
