No, there's no point appealing. You have no grounds to appeal, and you'll only end up losing a LOT more money. Filing cases in Canada isn't cheap.
Consider this an expensive lesson and move on with your life. A misrep ban doesn't mean that you have no chance for a visa to some other country, but you're correct in thinking that things will be more difficult now.
Always tell the truth on visa forms. Most countries will ask you about prior visa denials and if you lie about it, you'll end up getting banned from more countries.
However, there is no need to volunteer information that isn't asked. Like I said, 90% of countries (certainly most developed countries) will ask you about prior refusals, but if the visa form doesn't ask a question, you don't have to tell them.
Just make sure you always fill out visa forms honestly and accurately.
