To the best of my knowledge: Yes, you can expect a happy ending at those places, but you should expect to tip for anything beyond the basic massage. Generally speaking the "door fee" which runs roughly $60/hour usually goes to the house, and the lady giving you the massage earns her money in tips. If you want her fully nude with body slides and a release, you can expect to tip about $100-120.
Again this is just rough idea of massage parlours in Ottawa in general to give you an idea of what to expect, but for specifics, you need to check with the particular parlour.
