I am living in Scarborough and applied for my citizenship in Jan 04. The file has been transferred to SCarborough on Apr 30, 2004. Now I plan to move to London, Ontario will there be any delay if I give an address change. Thanks

If you change the address now, they will transfer your file to nearest office to London and that will certainly take some time. If you can it is better to just leave the address as is if someone you know will be living at your current address or may be redirect the mail for next one year
