Are there options to travel to Canada from the US to meet family under covid-19 restrictions?

I live in the US. I want to visit Canada to meet family and to get married to my fiance. My family members are permanent residents. My fiance is a citizen. I am not a Canadian resident/citizen.

According to guidance from Canada, one criterion of eligibility is being an immediate family member of a Canadian resident. That includes a dependent child. A dependent child only qualifies if you are under 22. I am older than 22.

Alternatively one is also admitted if there is a Canadian spouse/common-law partner. But that is exactly why I am going to Canada - to get married.

Besides that, foreigners can travel for "essential travel" which is described as

travel for reasons that are non-discretionary and non-optional. The emergency orders under the Quarantine Act do not allow people to travel to Canada for optional or discretionary reasons, such as for tourism, recreation or entertainment.

Does traveling to marry qualify as essential?

Is there a way to petition for admission to Canada under these criteria? Is there some other option?
