If you're referring to the ban (החרם תרימם) in the Torah (Deuteronomy 7:2), the Torah itself gives the reason (Leviticus ch.18, and Deuteronomy ch.9 and 18). It was because of the wickedness of the Canaanites, who engaged in human sacrifice, sorcery, and every form of lewdness including bestiality.
Whether God really did punish the Canaanites or reward the Israelites depends on whether The Bible should be read literally.
If the Books of Exodus and Joshua really were written by Moses and Joshua respectively, and if Moses and Joshua really were in communication with God, then the Bible should be read literally. However, scholars say that the books were written many centuries after the events they are said to describe, and simply depict a glorious, legendary past for the Hebrew people.
Moreover, most scholars now say that there never was a military invasion of the land of the Canaanites. They say that the Israelites were rural Canaanites who left the region of the rich coastal cities, to settle in the hitherto sparsely populated hinterland. If there was no Hebrew invasion, then God did not really reward the Israelites or punish the Canaanites.
Military: They were commanded by God to take the land from the Canaanites (Deuteronomy ch.1 and many other passages). Spiritual: they were commanded not to imitate the ways of the Canaanites (Leviticus ch.18 and many other passages).
Through Trade and Conquest.
The Canaanites occupied Canaan before Abraham (Gen. ch.12). They were descendants of Noah through his son Ham (Gen. ch.10), although Noah had actually bequeathed the land to the descendants of Shem (Rashi commentary, Gen.12:6). Thus, the Canaanites were usurpers.
Ownership of land changes hands over time through the fortunes of war. Ultimately ownership is considered to be defined by occupation, but normally never on the basis that a claimant's national god supposedly promised the land to his people. For thousands of years, the Canaanites had owned the land, but through either conquest (the biblical version) or peaceful infiltration (the archaeological version), the Hebrew people came to own a large part of the land and built the nations of Israel and Judah on the parts that they occupied.

At first - the Canaanites. Later, the Israelites.
They fight them to figer out who may clam the land
The exact date unknown. Some estimates place it at around 1300 BCE to 1100 BCE. There is also a growing theory that the Hebrews never fought the Canaanite, but that they WERE the Canaanites. Jewish tradition, however, holds that the Hebrews were not related to the Canaanites.According to Torah-chronology, Joshua fought the Canaanites from 1272 BCE until 1265 BCE.
A:The biblical reason for this is that God promised the land of the Canaanites to their forebears. The real reason is surprising! Archaeologists and scholars have ascertained that the Israelites were actually Canaanites themselves, and had migrated from the region of the rich coastal cities, to settle peacefully in the hitherto sparsely populated hinterland - they had not come out of Egypt to invade and conquer the Canaanites at all. Centuries later, after the Hebrew people had long forgotten their real origins, they created legends of their supposed ancestors, their sojourn in Egypt and the conquest of Canaan, just as this tradition says that God told them.
According to the Bible, Abraham.
First the Canaanites, then the Israelites.
A:According to the Bible, the patriarchs Abraham, Isaac and Jacob were indeed the first Hebrew leaders. The main problem with this assumption is that they never existed. Archaeology and history show that the stories of the patriarchs could not have happened. If Jacob and his twelve sons had existed and if he migrated with them into Egypt and their descendants were enslaved, this would necessitate the Exodus from Egypt and the conquest of a new land. However, nearly all scholars say there was no Exodus from Egypt as described in the Bible, and no conquest of the land of the Canaanites. The Hebrew people were themselves Canaanites who migrated from the region of the rich coastal cities and settled peacefully in the hitherto sparsely populated hinterland. The legends of the patriarchs developed in Israel centuries after they time they supposedly existed, as did the legends of the Exodus and the conquest of Canaan.
