I mean the schedule A background form. Sorry for the mistake
I provided my Schedule A upfront but many people have been asked to submit a new one. That's a good sign that someone is looking at your file. If you already provided the file with your original application, review it for completeness & accuracy. Many people left unintentional gaps, for example, in 8) Personal history or 12) Personal addresses.
Although you didn't travel outside of Canada, here is my response to an earlier but similar question:
Review your original form for any gaps in time. Typically, they want all periods covered and if you left gaps, fix those in a new form. Make it orderly so the agent can clearly follow it. Depending on the reasons why you may have left gaps in your original form, you may want to also provide a letter of explanation. You need to complete it accurately & truthfully. If the gaps were simple errors, you may want to say that in a letter of explanation -- or perhaps you weren't sure what to enter as an 'activity' so you left them out because you were not 'doing' anything in particular. For example, 'Unemployed' or 'Job Searching' are legitimate 'activities' if you were not Studying or Working or Visiting. You can add an extra page set up in a similar table format to continue your details if you run out of room. If you only spent a day or two in a country as you were travelling to or from somewhere, you should not have to report it. They are looking for where you lived & what you were doing when you were there. If you are still concerned about it, say in your LOE letter that you travelled to X & Y countries but only for a few days but leave it off the form. Make sure that each entry overlaps with or is sequential from the previous one:
Jun 2015 to Dec 2022
Feb 2014 to May 2015 (May then Jun above, sequential)
Jan 2013 to Feb 2014 (Feb overlaps with above)
(Of course, on the form you’ll use numerical months, not as I’ve illustrated here.)
Just double-check your entries and you will be fine! Lots of people have been asked to resubmit this form for gaps, so relax & be as accurate as you can. Best wishes!
