The local economy is based almost exclusively on agriculture.[1]
History
Settlement began in 1835 with the arrival of Irish immigrants. In 1846, the parish was founded and named after Martha, the sister of Lazarus, since the neighbouring parish was called Saint-Lazare.[1]
That same year, the Municipality of Sainte Marthe was created out of the Municipality of Rigaud, but abolished on September 1, 1847. In 1851, its post office opened.[1] On July 1, 1855, the municipality was reestablised, which became a parish municipality in 1857.[5]
In 1928, the village itself separated from the surrounding rural parish and became the Village Municipality of Sainte-Marthe.[6]
On December 27, 1980, the parish and village merged to form the Municipality of Sainte-Marthe.[1]
On 5–6 April 2023, a storm of black ice caused 623 person to lose electricity.[7]
