Well I just got the following automated response. FYI to anyone else whose file is with Niagara Falls, be sure to include your full name, date of birth, application number and UCI number in your email if you email them.
Thank you for contacting Immigration, Refugees and Citizenship Canada (IRCC). Please note this is an automated message.
This mailbox should only be used to
provide documentation related to a citizenship application or to provide a reasonable explanation for missing or being unable to attend a scheduled event (with documentary evidence). To facilitate the processing of your request, you must include your
full name, date of birth, application number and UCI number. Please resubmit your enquiry if your original email did not contain these information.
Take note that any requests received other than the above will automatically be deleted and not processed.
Please note that there is no need to reschedule an online test as long as your invitation is still active.
If you are experiencing technical issues before accessing the online test, please contact
IRCC.CitOnlineTest-TestenligneCit.IRCC@cic.gc.ca.
For all other inquiries regarding your application, we invite you to complete the
IRCC Web form.
Thank you,
