I am a Canadian citizen with a felony in the u.s. which I was on probation. I am now back in Canada after a voluntary departure from the u.s. and want to travel Europe... Can I still enter Europe with a felony from the states. It wasn't drugs or guns charge

Europe is not one country, it is like saying you want to enter the "Americas" which is often considered Canada, Mexico and US. All have different immigration requirements.

You will need to consult the embassy and immigration requirements for visa's in the nations you want to enter.
