My incremental expenses -- that is, what it cost me to go from Detroit to Toronto; obviously my employer paid to get me to Detroit -- were reasonably well recorded, although finding receipts for things that old might have been challenging. When asked about my expenses, I itemized what I spent according to my files in Quicken (hooray for good record-keeping!), and T3 elected to reimburse me from those records.
Today I received a US dollar check for $240 in reimbursement of those travel expenses. I appreciate it.
