I would like to know why we come back from Israel so many times, we went 3 times to Israel and we always leave. I don’t know why? We want so badly to stay and we want that it will working well, but each time there is something that we have to go back to Canada for.

I obviously don't know you so can't answer a proper answer. Maybe Hashem has a task for you in Chutz laaretz? Talmud tells us that Eretz Yisrael is acquired through suffering, if you want to acquire Eretz Yisrael for you and your family you have to be ready to suffer. Maybe that is what's missing?
