谢谢回复，我2018年也是研究了好久才得出我2017年是non resident for tax purposes，并且不需要报税的结论。虽然我2017年登陆了，但是我不是过来settle（定居）, 而且也没有注满183天。所以我应该归为non resident:
You are a non-resident for tax purposes if you:
- normally, customarily, or routinely live in another country and are not considered a resident of Canada
- do not have significant residential ties in Canada
- you live outside Canada throughout the tax year
- you stay in Canada for less than 183 days in the tax year
Non-residents of Canada - Canada.ca
Information about the income tax rules that apply to non-residents of Canada.
然后关于是否要报税：
You must file a Canadian income tax return if you:
- have to pay tax
- want to claim a refund
我当时琢磨了一下，我2017年的银行储蓄利息总共400多。不足以需要交税。那根据此，我当时的结论就是不需要报税了。
如果有其他的说法， 请告诉我一下，并且给出说法来源。
