And where did the Canaanites get their religious influence?

From their neighbors, mountains, skies, rivers, rambling lunatics - fucking everywhere, like everyone else.

Since its already implied that jews were capable of taking a minor god from an already existing pantheon and meshing their traits to suit their spiritual needs why wouldn't the Canaanites do the same? 

This makes no sense. The "Jews", more specifically Israelites, were Canaanites.

The Egyptian pantheon predates most if not all known religions in the surrounding region.

So? Early Egyptian religion is derived in large part from East African cultures and religions.
Besides, in the case of Yahweh, it's more likely that he is rooted in ancient Mesopotamian religion, rather than Egyptian.
