This information came from my wife who is an immigration consultant working in Ontario Canada
A person can say he was deported when he actually just received a removal notice (usually it says you have violated Rules XXX and you no longer have a legal temporary status in the USA. You are required to leave USA on this day.) but a formal deportation order is a different thing. usually you get it when you are arrested and detained for a period of time. You will not be released until you are removed directly.
If you leave voluntarily, your Canadian visa might still work, but if you have been issued a deportation order, you most likely won't be able to enter Canada.
