@High Seas,
i've made reference to legal residents who dodge taxes on the immigration threads before, it's common among legal immigrants who come from countries where they don't trust the government, or areas where the black market and an under the table cash only system is common
i worked with some african folks who had got their canadian citizenship, the father worked a legitimate job, and paid taxes, but his wife and daughters (who worked on the packing line at the greenhouse i worked at) worked for a "contractor" for cash, a chinese lady who also had citizenship asked me if she could go on the books, so she could build up time for a maternity leave, before that she also worked for a "contractor" for cash, unfortunately, for her, she miscalculated and the work ran out before she got her legitimate time in
