He was active in a family business inherited from his father, and also served in the Lower Canada militia during the War of 1812, at the Battle of the Châteauguay.

[1][2] His family was active in politics: By 1810, Raymond had entered his father's business in manufacturing and the sale of goods.

They were involved in processing potash, sawmilling, and the sale of household and manufactured goods to local farmers in return for wheat.

That changed in the late 1830s, when a combination of wheat blights, an economic downturn, and property damage as a result of the Lower Canada Rebellion interrupted his business.

His units were called into service later that month, as part of the Canadian and First Nations forces at the Battle of the Châteauguay, which prevented an invading American army from capturing Montreal.

His father, Jean-Baptiste Raymond, was the chair of a meeting in Huntingdon, called in opposition to the union; Jean-Moïse acted as the secretary.

He voted in support of the Ninety-Two Resolutions, a Papineau initiative, setting out their opposition of the Lower Canada government set up by the British government, and demanding more popular control, such as replacing the appointed Legislative Council (the upper house in the provincial Parliament) with an elected body.

He resigned his seat effective January 1, 1842 to become District Registrar for Leinster County, possibly for financial reasons.
