A word of caution: Home renovation cases are among the most difficult and time-consuming type of cases the Ontario Small Claims Court has to hear.  They often involve multiple issues, legions of deficiencies or incomplete work, dozens or even hundreds of photographs and competing assessments from various contractors, inspectors and even engineers.  All of this makes for a very difficult case for a try judge to adjudicate upon.
We say this not to dissuade you from litigation but rather as a cautionary note and something to take into account when looking to settle a matter without the need to go to trial.
