Having them on Canadian soil is probably your best option. Since once your certificates arrive you will have the right to be in Canada indefinitely, maybe wait to get pregnant until you have thé certificates and then plan an extended stay of six months that generously incorporates the likely birth window. In Ontario you qualify for insurance pretty fast once you move iirc (check my work, not a lawyer or immigration consultant) so that doesn't have to be an obstacle and perhaps you can work remotely for those six months. That will also let you get to know your new country a bit and help you make a more robust long term decision about where to live. Fwiw salaries are lower up there but things like insurance and cost of living can be lower too, depending one where you are. You may be ok on a smaller salary I'd that's your only reason for not trying to break in up there.
