About 6-7 months ago, a friend of mine got a job with the Canadian Government at an hourly rate. However, due to the Phoenix system debacle, he wasn't being paid for his work.
This problem has several stages, at first his "pay"stubs indicated he did 0 hours of work at $0/hour for a total of $0. After a few months of this (and repeated calls to a Phoenix people), they updated his paystubs to indicate the correct amount of hours at the correct rate, but they didn't actually deposit any money.
Eventually, they started paying him, but I believe they are still about 4-5 months behind on pay. (There is a seperate question regarding an error on his paystubs, but I'll make a second post).
He got letters from the bank proving how much the Government has deposited during the past year or so. I'm not sure if he has letters from the government which agree.
The (potential) issue is this:
When T4 slips are generated, if the T4 claims that he has been paid, does he have recourse to contest this, or is he required to pay tax despite not actually being paid?
