Used Canon Vixia - tips

Just got this Vixia HF R800 of marketplace, and didn't realize it doesn't have any lighting/viewfinder/or hot/cold shoe...(I know I should've done more research)

Is this overall a good camera? How do I get good footage in low light situations with no light??

I bought this as a camcorder for homevideo style footage of my wedding ceremony and reception (great audio not expected).
