You will have to show that you have a plan and a track record of being able to earn a decent income. You earning an income eill likely result in losing subsidized housing. Your story is pretty complex. You had a previous sponsorship attempt, a child in Canada and got married to another Canadian relarively quickly. I assume you also have child support payments.
In Canada, social assistance benefits are administered provincially. The Immigration and Refugee Protection Regulations (R2) define social assistance in broad terms, but render someone who is in receipt of social assistance for a reason other than a disability ineligible to be a sponsor under the family class [R133(1)(k)]. The intent of R133(1)(k) is to bar persons whose primary or sole source of income is “social assistance” benefits from sponsoring a relative under the family class. There are various programs and services provided by P/Ts which confer benefits that IRCC does not consider to be social assistance for the purposes of imposing a bar on sponsorship.
Examples of these would include, but are not limited to:
subsidized housing
tax credits
child care subsidies
other benefits which would be widely available to residents of a P/T, including persons who are employed
If a sponsor resumes providing for a sponsored member of the family class who had been, but is no longer in receipt of social assistance, they are still in default until such time as social assistance authorities in the /P/T confirm that the debt has been repaid in full.
YES, a hundered times yes. Except disability allowance and EI, most of every other benefit is a social assistance. Think this way, if living subsidy does not qualify than what else would? Also IRCC takes these very seriously.
