Montreal is very romantic… a great place for a Wedding / Vow Renewal.
And YES just like other places in North America someone from outside of the jurisdiction / country can get married there if they meet the current requirements. (No Tourist Visa is needed for US Residents… just your Passport)
First off a few things you’ll want to know… so you can make an informed decision.
Montreal is in the Province of Quebec… which is all what is left now of what was once New France (most of the Continent of North America between 1534 and 1763). This all changed in the mid 1700s with the Seven Years War (known as the French & Indian War in the USA) when the French lost “the continent” to the British

After all that… just Quebec remained predominently French speaking… and the British made concessions to the French by allowing them to maintain some of their rights & culture (such as Language, Religion, and their Judicial System… which is known as Civil Law… vs the rest of the continent that uses Common Law)
As such, there are some marked differences between French Society in Quebec and the rest of North America.
And that includes Marriage. Altho you can marry either in a Civil Ceremony or a Religious one in Quebec… you will not be able to legally change your name (assume the one of your Husband)… without processing a Legal Name Change with your own State etc.
This is because in Quebec Society names belong to the person from the cradle to the grave… as a way of maintaining historical french surnames… and the lineage of the Mother as well as the Father (altho it doesn’t at first glance appear that way… in fact Quebec is very progressive when it comes to Women’s Rights)
So that is the biggest issue… if you want to Mrs HubbySurname after your marriage… you really should marry in the USA or elsewhere in Canada (the Province of Ontario… is a mere 45 minutes west of Montreal).
If you really do want to keep your maiden name forever… then there is no issue in getting married in Quebec whatsoever.
