I have no idea what childcare costs in Manitoba, but you can contact the provincial government and request a childcare subsidy. (That's what we call it in Alberta at least.) If you qualify, they will help pay for childcare. Just be forewarned, not all dayhomes/daycares accept subsidy and depending on your area, there may be a waiting list for a centre with subsidy. You can also use subsidy to cover childcare to job hunt, interview, etc.
If you receive any child support from the father, you will have to declare that on the application - along with all forms of income (i. e., job, alimony, etc.)

Just a note - if you are living with another adult (doesn't matter if it's a boyfriend, roommate, your mom, etc ANY adult) you MUST put them on the form. If you don't and the government finds out, they will yank your benefits. It's extremely difficult to get them back after that. We know a lady this happened to (she didn't list her boyfriend) and now years later, the government won't give her any benefits besides the tax credit.
