If the course was required by your employer to benefit your work, have your employer provide you with a completed & signed T2200 form (which YOU keep) and then you can claim the course cost on Form T777 Employment Expenses. ACoP registration fee sounds more like a membership, if it's an annual payment. Not sure if this is deductible - what does it say on the receipt they gave you? Does it say for tax purposes? If not you can call them and ask.
