If somebody who's a single parent is in a new relationship, unless they're in a new relationship with somebody who has no income, they're going to lose. If they move in together or get married, they will lose quite substantial amounts of CCTB. The numbers are large for low-income people because, if you're talking about a single parent with an income of $20,000 or $30,000, around that range, the marginal tax-back rates on CCTB are really quite high. Marrying somebody who has an income of $30,000 also would cause quite a big loss in benefits.
