one return per envelop
You should have filed your returns in separate envelopes even though you are husband and wife of one family.
Your return may not be properly assessed based on the above assumption that one return per envelope. Or it could possible that it took longer time assessing your return.
You have three possible options:
1. Call 1-800-959-8281 if your tax return has no residence issue,
from Monday to Friday (except holidays)
from 8:15 a.m. to 5:00 p.m.
2. If you filed tax return last year, you can register CRA e-services "My Account" with the required information, and then you can review all your tax related information online anytime you like.
3. If you have time you can drop by at 875 Heron Rd, CRA has counter services to answer individual's questions on tax returns. Please call them before you go to make sure that they still provide this service without appointment .
Hopefully it answers your question.
Good Luck!
