Services available in Port-Menier are: general and grocery stores, gas station, banking (Caisse populaire Desjardins), car rental (Location Sauvageau), restaurant, and lodging.
But no significant development took place until 1895 when Henri Menier bought the island and hoped to set up a seignory that could be self-supporting.
He invested a substantial amount of money to construct a sawmill to service the logging operations that harvested softwood timber for building lumber and Wood pulp for the manufacture of paper products.
The town had its own hospital, school, Roman Catholic church, general store, bank, bakery, hotel, plus homes and rooming houses for the workers, and a 30-room Scandinavian-style mansion for himself.
