These are the most common Ontario Lottario pairs organized in two different categories. The first category of pairs contains numbers that are not consecutive while the second category is the pairs made up of consecutive Ontario Lottario numbers.
Under each set of pairs you will find some interesting details such as how many times that particular pair was drawn during all previous Ontario Lottario results, one or more links to the Ontario Lottario results where the pair was drawn and how many draws have passed since the pair last came out.
