In the earliest oral history, the Algonquins were from the Atlantic coast. Together with other Anicinàpek, they arrived at the "First Stopping Place" (Montreal). There, the Nation found a "turtle-shaped island" marked by miigis (cowrie) shells.
The Iroquois or Haudenosaunee were centred from at least 1000 CE in northern New York, but their influence extended into what is now southern Ontario and the Montreal area of modern Quebec.

1535 – October 3, Cartier climbs up the mountain on the island of Montreal and names it Mont Royal. He wrote: "Nous nommasmes icelle montaigne le mont Royal." (We named the said mountain Mont Royal.) The name Montreal is generally thought to be derived from "Mont Royal", the name given to the mountain by Cartier in 1535.
1575 – In his "Cosmographie Universelle de Tout le Monde", historiographer François de Belleforest is the first to use the form Montreal in reference to this area. Translated, it would read: "let us now look at Hochelaga, ... in the midst of the countryside is the village, or Cité royale, adjacent to a mountain on which farming is practiced. The Christians call this city Montreal...".
1639-49 – Sainte-Marie among the Hurons in use. The establishment of Montreal was part of a large missionary movement based in France. Over the next 40 years after Quebec's founding, dozens of missionary posts will be built in Huron territory.
1641 – On May 9, Paul Chomedey de Maisonneuve and his recruits leave La Rochelle in two ships. Maisonneuve boards one with a secular priest for the Ursuline convent and twenty-five men; Jeanne Mance and another woman, the Jesuit father La Place, and 12 men are aboard the second ship. At first the two ships manage to stay together. However, after eight days they are driven apart by the winds. François Dollier de Casson writes, "the ship carrying Mademoiselle Mance experienced little other than calm weather, M. de Maison-neufve’s encountered such violent storms that it had to put back to port three times."
1641 – A third vessel is sent by the Company from Dieppe, containing ten men. It is eventually the first to reach Canada.
1641 – Maisonneuve's ship only arrives at Quebec City on August 20. Hope of their arrival that year had already been lost. Fall storms delay plans for the settlement of Montreal.

To the surprise of all, Tessouat requests baptism and a Christian marriage. His conversion is greatly prized because of his importance as chief and because of his former hostility. Great solemnity is therefore observed in the ceremonies on March 9. Maisonneuve grants land to Tessouat and provides him with two men to help cultivate it.
1643 – On June 9, the first persons are killed at Montreal during an attack by the Iroquois. Forty Iroquois warriors surprise six Frenchmen hewing timber with gunshots to the fort. The Iroquois kill three men and take the remaining three prisoners.

1643 – La Dauversière publishes a book on Ville-Marie, The Purpose of Montreal, that raises support for the project in Paris. Written in 1643, it describes the settlement shortly after its founding: "There is a chapel there that serves as a parish, under the title of Notre Dame.… The inhabitants live for the most part communally, as in a sort of inn; others live on their private means, but all live in Jesus Christ, with one heart and soul."
1645 – Treaty with the Iroquois. The peace is broken a few months later.
1645 – In October, Huron and Algonquin Indians break into the house of Pierre Gadois (Gadoyes) (1594–1667) on several occasions to steal food from him and beat him. Pierre returns to the Quebec City area from 1646-1647.
1645-46 – Tessouat spends the winter in Montreal where he planted corn. But he eventually withdraws to Trois-Rivières, urging others to do likewise, in the face of reports that Iroquois raids are imminent. This probably results from having heard that the French had abandoned non-Christian Algonquins in the 1645 treaty with the Iroquois.
1648 – First land concession, to the Pierre Gadois and Louise Mauger (1598–1690) household on January 4; the land consists of 40 arpents or approximately 300,000 square meters and the location of the property coincides with the present rue Saint Pierre in the east, Rue McGill in the west, Rue Saint-Paul in the south and rue Ontario in the north. Prior to this, the inhabitants of Ville Marie had lived a communal life working in the fields during the day and then returning within the fortified walls of the village at night.
1648 – Adrienne Du Vivier arrives; she and her husband, Augustin Hébert, are often referred to as "Montreal's First Citizens."

1652 – "July 29: Two Iroquois, having slipped in under the cover of the corn, attacked Martine Messier, the wife of Antoine Primot who, by defending herself courageously, gave the soldiers of the fort time to come to her aid and put the enemy to flight. She received six shots, none of which are mortal," wrote a Jesuit priest in his diary.
1653 – The Grande Recrue: Jeanne Mance takes money that was intended for the hospital and uses it to recruit a hundred people; the contingent arrives at Ville-Marie on November 16. Of the 95 who embark in Saint-Nazaire, 24 are massacred by Iroquois; 4 drown; one is burnt when his house catches fire.
1657 – On 28 January, returning from mass, Jeanne Mance falls on the ice, fractures her right arm, and dislocates her wrist. Although cured, Jeanne was unable to use her arm. Because of this infirmity she considers retiring as head of the Hôtel-Dieu de Montréal. She waits for the return of Maisonneuve, who had set out for France again in 1655. He returns only at the end of July 1657, together with the first parish clergy for Ville-Marie, which consists of three Sulpicians under the leadership of Abbé Queylus.
1658 – In November, a Ville-Marie tribunal convicts René Besnard dit Bourjoly of casting a spell of impotence over Pierre (Gadoyes) Gadois, a rival for the hand of a woman he had courted. Besnard is flogged, imprisoned, and sentenced to death, although the latter punishment was reduced to banishment. In August 1660 François de Laval annuls the still-barren marriage of Pierre Gadois and Marie Pontonnier on the grounds of "permanent impotence caused by witchcraft". In their later marriages to others, this "sterile" couple had a total of 25 children.

1661 – A boys' school is founded by Gabriel Souart, who prides himself on being the first schoolmaster of Ville-Marie.
1665 – Paul de Chomedey de Maisonneuve returns to France. The missionary dreams of the first Montrealers had given way to the lure of money to be made in furs. Although Maisonneuve had lived in Ville-Marie for twenty-three years, he never became a landowner, choosing to dedicate himself to his religious cause. Back in Paris, he lives in a secluded cabin that he built, and remains humble and discreet until his death.
1666 – According to census of New France, Ville-Marie now has 582 inhabitants. 24 of the 111 families living in Montreal had already been formed in France. A few houses, flanked by a windmill and fort, and connected by a footpath where now runs Rue Saint-Paul, represent the beginnings of Ville-Marie.
1667 – Boucherville is founded as a seigneurial parish by Pierre Boucher. Pierre Boucher begins farming this year but does not receive his seigneury until 1672 when he builds a palisade to protect the community from the Iroquois.
1667 – Almost from its foundation, pelts were bartered in Montreal, but it was after 1667 that the town becomes a centre for trade. An annual market for pelts takes place in June on the common of Pointe-à-Callière.
1670-80 – At first trading is done in people's home, but traders soon set up stalls between Saint-Paul and the Little St. Pierre River, west of the marketplace. Natives – some 900 of them in 1672 – camp on the point, not far from the seigneurs’ gardens.
1680-85 – More and more voyageurs, coureurs des bois and missionaries were exploring the regions upriver from Montreal. As the new territory opens up, part of the fur trade shifts toward the Great Lakes. Fewer and fewer natives came to Montreal, and the annual fur fair became less popular from 1680 to 1685.
1686 – Pierre Troyes leads an overland expedition from Montreal to the shore of Hudson Bay where he takes many of the Hudson's Bay Company's forts by surprise. New France would wage several naval raids into the bay the following years and almost drives the English from this part of the continent.
1687-89 – A wooden palisade is erected to protect the town. Some years after the city was founded, the initial fort is abandoned and the town continues its development at Coteau Saint-Louis, around which wooden fortifications are built in 1687 and 1689.

All appeals, and all serious offences, such as theft or murder, were to go for trial before British courts-martial, one of which was to be constituted monthly for each two subdivisions.

I presume there is hardly a house in all the upper city without modern plumbing, and yet in the lower city not less than half the homes have indoor water-closet privileges. In Griffintown only one home in four is suitably equipped, beyond the canal (in Pointe-Saint-Charles) it is but little better. Our city by-law prohibits the erection of further out-door closets, but it contains no provision for eradicating those already in use. With sewers in almost every street, no excuse for permitting this state of affairs to continue now exists, except it lies in neglect and in greed."
