Linking a bank account to paypal.

I've been using my current paypal for some time now. I can currently do everything on it without a problem (sending money, receiving money.) I fear that for some reason my account could get frozen and I would just lose all the money because all of the info I registered the account with is fake. This is why I want to just transfer the money I have in this account to a new paypal I will create which will have my real information. I would want to connect this new paypal to my bank account so I can put money in my bank account every week. I have some questions though;

1. What exactly do I have to link my bank account? Its cibc and I live in Canada.

2. If I do this are there absolutely no restrictions on my paypal transactions (money sent, money received)?

3. Is there a limit to how much I can put into my bank account?

4. Let's just say, for example, someone sends me 1000. I put this 1000 into my bank account but someone tries to chargeback on paypal. What would happen?

5. Can paypal ever force money from my bank account?

6. What happens if I try to put USD paypal money into my bank account but my bank account is canadian? Most of my paypal currency is USD.

 

2. If I do this are there absolutely no restrictions on my paypal transactions (money sent, money received)? None at all
