Did you get a Confirmation like this :?
Dear XXXX,
This confirms that your application has been received by Immigration, Refugees and Citizenship Canada (IRCC) on
__________________(yyyy/mm/dd).
When will IRCC contact me?
You are expected to provide a COPY of your passport with your electronic application. If IRCC needs your physical
passport, IRCC will request that you submit it to our office. IRCC will also contact you if we require additional information,
documents or an interview. For general guidance on what to expect, you can visit
or consult the “What Happens Next” section of the instruction guide
associated with the application form you used.
*******
This seems to be generic and you do upload your passport in online application anyway. If not, how did you send the copy to them?
***
You should contact the Canadian embassy in USA via email. They do reply.
