"Under the new system, a family with one child under six years old that made $30,000 last year will get $6,400 per year, while a similar family that made $90,000 will get about $3,150. While that represents a substantial difference, the two families would have received $4,852 and $2,201 respectively.
That means the lower income family will receive $1,548 more under the Liberal plan, while the higher income family will receive an additional $1,100. The Liberals could face questions over why the lower income family isn’t receiving a bigger boost, particularly given how much closer they are to the poverty line.
Similarly, a family with one child under six and one over six that made $30,000 last year will receive about $3,250 more than they did under the previous system, while a similar family that made $90,000 will get an additional $2,505."
