我不清楚加拿大的劳工法。 这种情形我建议如果根据劳工法你有应付而未付给他的钱款， 尽快付给他。
加拿大的bad check law 我不熟悉。 你可以查询一下。 我给你一些美国的相关法律做参考。
民事：
加州的civil code 允许the receiver of a bad check 得到支票金额的三倍民事赔偿， 但赔偿的总金额不超过1500， 如果sufficient notice is mailed or delivered to the person who wrote the bad check. 以上所说的赔偿是 in addition to collecting the value of the check。你的这个金额的管辖法院是小额钱债法庭。
If sue for the amount of the check + bank fees --- file a small claims case right away.
If sue for the amount of the check plus damages-- first send a demand letter to him.
如果上庭， 你至少准备的证据是:
- The bad check;
- A copy of the demand letter;
- The certified mail receipt; and
- Proof that a good faith dispute does not exist.
刑事：刑事定罪的根本在于他写支票的时候已经明知支票会跳票， 怀有欺诈的意图。
In California, it is a crime to write a check knowing that you have insufficient funds and the intent to defraud.
If the prosecution can prove that drawer (他） knowingly wrote a bad check with the intent to deceive payee （你） out of money or property, the drawer will be convicted.
payee可以向 police department, sheriff's office or 行为发生地所属county 的 district attorney 报案。
