Material to patch fill hole (L5L 5P5)

Just took out old toilet roll holder from my bathroom wall; I’m looking for materials like wire mesh, wood and not sure what I need to fill it; if anyone can help me do this as well; much appreciated. I think I have to get the item to fill up holes as well on top of the drywall? I’m in mississauga Oakville border area near Costco.
Can you help with this request?
