Canadians are admited to the US as visitors with an implied B2 visa. If you cross by land, it will not be stamped in you passport. The visa is good for six months. However, if you tell the immigration officer that you expect to stay for six months in the US, they will probably make it very hard for you to enter the US. Having said that, once you are in the US, you can extend your B2 visa for up to another 6 months. To do that you will have to apply for the extension prior to your original 6 months ending.
If you do extend your B2, you may be subjected to some more scrutiny at the border the next time you cross, depending on which border officer you get at the border. Also, if you leave while on the extension, you may not be able to come back.
As a Canadian, you are not subjected to a lot of scrutiny when you enter by land. They really do not know when you left. If you ask for an extension to your B2, then you will be in the system, which may not be all that good a thing.
If you may marry your "opposition", then you can do that there and ask for an Adjustment of Status, leading to permanent US residency (Green Card) after you marry him there. Just be sure you marry him after three months of entering the US, or they will claim that you entered the US as a B2 visitor under false pretexts. Do not even send out invitations to your wedding or anything else that will make an officer believe you had an intention to marry prior to your being there for three months. Also make sure you get the date you entered stamped, not by asking for it, but by flying into the US from a Canadian airport. If you tell the border officer that you intend to marry a US Citizen while entering as a visitor, he will most likely not let you in and place you on a blacklist.
