Water proofing a pack

I recently brought a WE Breakout pack. I was thinking maybe I should waterproof it.
What is the best way to waterproof a canvas pack?
Or am I just wasting my time, and it won’t leak to much or at all?
I have been on a few walks with it and so far have been very lucky with the weather.
Thanks
