I do have sufficient documentation that shows we've been living together, going on trips together, members of social clubs together, living at the same address in Canada for the past 6 years. My supposition is that if I can't cross, it'll be becauee I'm an American and NOT essential -- common-law-husband status notwithstanding.....
I'll check with a few Canadian consulates next week and see if my supposition is correct. Thanks for your input. Be safe.
