Chances are you will just need to answer some questions at the bank (how did you get the money, can you prove you are in legal possession of the money) and show some ID and SIN at the bank when you deposit it and possibly sign a statement swearing you are in legal possession of the money.
If at all possible, bring whatever proof you can to show that you are in legal possession of the money. If it's money as a gift from friends/family, you may ask them to give you a written and notarized statement especially if the sum is over $1,000.
The biggest concern of the bank taking the cash is just to ensure it is legal tender and you are in legal possession of it. $10,000 is a large sum so you will get some attention for depositing it all at once in cash.
