In 1829 Britain and Augustus Newell acquired the lands on which the business portion of Saint Joseph was later built. Newell built the first hotel in 1831 known as the "Mansion House". The government surveyed the land in 1830, and Britain laid out the plat of the village in 1831 calling it Newburyport.
Britain also built a warehouse and bought and sold real estate.
The name of the town was changed to Saint Joseph in 1834. Due to changes to the Michigan Constitution adopted at that convention, he was elected to a one-year term as the eighth Lieutenant Governor of Michigan with Governor Robert McClelland.
Britain never married and resided in Saint Joseph until his death there in 1862. He is interred at Saint Joseph City Cemetery, Saint Joseph, Michigan.
Calvin Township in Cass County, Michigan, is named for him.
As a Democrat, Britain was a member of the Legislative Council of Michigan Territory from 1832 to 1835, Michigan Senate from 1835 to 1837, Michigan House of Representatives from 1847 to 1851, and member of the Constitutional Convention of 1850.
