Well that's because you're looking at the old provincial parent subsidy program, which is unrelated. You seemed to have gone down a rabbit hole. The 10$ a day childcare was just instituted a year ago roughly with the federal govt and will be fully fledged over the next 5 years with half a billion invested. This will result in the average daily cost for childcare being 10$ per family by the end, but savings for families are already being seen. There are no income limits currently and all can access, regardless of income. This is modelled after Quebec which has had this for decades, and is being rolled out in all of the other provinces and territories over the next 5 years. Quebec found they did not have to increase taxes to fund the program as they garnered more tax income from the increased participation in the workforce by parents. This has been well documented.

Every province and territory has a deal with the feds now for 10$ a day childcare for all families: feel free to peruse:

Nevertheless, participation is early but heavy. My own sister who lives in Alberta, and her family make great money around $200,000 a year. Her childcare costs already went down from $2000 a month to $500 with two kids. She could go back to working full time. Hell, some provinces like Ontario are actually giving retroactive rebates for parents who paid more before the program started. Overall while the program is young it outstrips the weakly funded Maine subsidy program by leaps and bounds already. Even the most conservative provinces in Canada saw the economic value of the program, and early stats show economic benefit.
