Knowing that you wanted to sponsor your parents you could have prioritized working versus taking courses. That is personal choice. The LICO was already reduced to a very low level for 2020.
My boyfriend who lives with me part-time has earned more than the minimum required amount for the last three years, can he and I together co-sponsor my parents (he is not my fiance yet, but we have been in relations together for a few years now and he has lived with me most of the time)? would my boyfriend be counted as my common law partner? is there any documents or conditions particular required in that case as proof to show that he is my common law partner? what are required if I would be eligible to co-sponsor my parents with him? do I still need to submit my own NOA for last years too, or would his NOA of last three years be enough for it? Do you know?
