These are odds using the American betting system, which is the most common in Canada as well. In essence, a "plus" bet means that for every 100 dollars/units you bet, you will get that amount as a profit if you win. A "minus" bet means you will need to place that many dollars/units to get 100 as a profit if you win. So a +200 bet will get you 200 dollars/units in profit if you are correct.
