Well given that it doesn't impact your physical presence in Canada, IMO I would say it would be a non-issue.Guys i just discovered an error. I went to the UK directly from Canada and came back from the UK to Canada for two weeks in 2014 which i put on my days out of the country on my application and i just discovered while looking at my passport that i actually stepped into France for a few days and came back into the UK and i did not declare that. Would this be an issue? What to do as the stamp shows entered and left France within the period i already declared out of Canada in the UK only. It doesn't affect my number of eligibility days as its the same but would this be flagged during interview?
What I'm not sure about is whether it's worth correcting this minor mistake using the webform. Since you have a stamp from France on your passport, there's a chance the officer would scrutinize it during the interview, but you could simply explain that on the spot.
Some folks forgot to account for complete trips and were still ok because they had a large buffer.
Your call.
