Sushil defended his crown in the men's 74 kilogram category which he had won at the 2014 edition in Glasgow, Scotland.
Botha was no match for Sushil, who pulled off a four-point move in the opening seconds of the first round.
The veteran Indian star then executed a series of two-point moves which gave him a 10-0 lead and the gold.
Sushil has won gold at the CWG final for the third consecutive time. He had won gold in the now disbanded 66kg category at the 2010 edition in New Delhi before winning the 74kg title at the 2014 CWG in Glasgow, Scotland.
In the 57kg division, Aware was dominant right from the start, pulling off three two-points moves in the first round.
Although the Canadian showed excellent technical prowess with a four-point move, it was enough to prevent Aware from taking a two-point lead into the break.
Aware however, made an ankle hold to execute the classic 'fitlay' move which saw rack up eight consecutive points.
That gave him a virtually insurmountable eight-point lead which proved too much for Steven to surmount.
