I was selected for review by CRA and while I have all my receipts and mileage logs, I can't find the T2200 for the employer I worked for at the time. I tried contacting them, but the Payroll people are on vacation, and I wouldn't be able to get a hold of them until they're back. The shop I worked out of also has closed so the Payroll staff have changed.

The expenses were for work-related cellphone, travelling to and between work camp/sites, trucking meals while away for 24 hours/day, and stationary for work-related paperwork. 

Aside from continuing to try to get a hold of Payroll, what else should I do until then? If they are unwilling to assist me, what other options do I have? Should I try to submit all my records without T2200 anyways?
