Unfortunately not because you won't meet the income requirement if you just arrived in Canada and haven't established yourself or filed a Canadian tax return. You could see if your mother gets a TRV. She needs to be able to finance her own trip and still have savings as well as show strong ties to her home country and a previous travel history. Assume she is not from a visa-exempt country. Just warning you the daycare rates can be brutal in Canada. All depends on where you are settling.
