Canadian Norwegians to the USA

My great grandparents Ole and Olea Pedersen came from Norway to Quebec, Canada in 1859, and settled in the township of Bury, Compton County, Quebec (about 20 miles north of the New Hampshire, US border). They lived there until 1863, when they traveled to Rock Creek township, Dunn County, Wisconsin, USA. I am looking for information on the usual means of travel that they might have taken in that time period. They lived in a settlement in Bury township that had numerous other Norwegian families that also left for the US after a rather brief stay.
