Is it possible?

So I'm still married to my  husband😒 but we have a baby coming on the way, is there a possibility that I can get him to pay for child support even if we aren't together anymore but still married? (Reason for still being married is that I am still hoping we could work out our marriage for the baby since we really didn't break up because we didn't love eachother it was because his parents manipulated him and ofcourse mamas boy gotta listen to his mommy so that's why he left me. Unless he ask for divorce, I won't be filing one unless I too decide that there's no more chance) Reason why I need to know if I can make him pay for child support is because I will be very tight on budget since I am starting my dental course soon and I won't be working full time.. So.. I live in Canada btw
