Ancestry.com has border crossing from New Brunswick to Maine and from Maine to New Brunswick. I looked for her under the surname Bois and Albert and looked for him and could not find either one going either direction. There marriage record shows the marriage in Canada 22 Jun 1909. The 1910 census says that she first came to the US in 1908, but that arrival also does not appear in the border crossing records, that I can find.

Dear Ms. Soule,
Thank you for posting your request on History Hub!
An immigrant woman automatically became a citizen when she married her U.S. citizen fiance. Her proof of citizenship was a combination of two documents: the marriage certificate and her husband's birth record or naturalization certificate.
If she began a naturalized U.S. Citizen before she married, beginning on September 27, 1906, the responsibility for naturalization proceedings was transferred to the Federal courts. For access to the records of Federal courts in Maine, please contact the National Archives at Boston (RE-BO) via email at firstname.lastname@example.org request a search for her naturalization records by including the name of petitioner (including known variants); date of birth; approximate date of entry to the US; approximate date of naturalization; where the individual was residing at the time of naturalization (city/county/state); and country of origin.
In most cases, the National Archives will not have a copy of the certificate of citizenship. Two copies of the certificate were created – one given to the petitioner as proof of citizenship, and one forwarded to the Immigration and Naturalization Service (INS).
Certificates of citizenship were issued by the Federal courts until October 1991 when INS took over responsibility for naturalization proceedings. All INS records are now overseen by the US Citizenship and Immigration Services (USCIS). USCIS maintains duplicate copies of court records (including the certificate of citizenship) created since September 27, 1906 and may be requested through the USCIS Genealogy Program.
We hope this is helpful. Best of luck with your family research!
