I want to know the step by step guidelines on how to prepare general ledger and how to do payroll (including links to EI, CPP and other payroll link) from start to finish. Thank you in advance for your reply.

This is a lot of ASK if I may say so.
You can achieve this by:-

1) Purchasing a good Accounting Textbook, plus
2) Enrol in an Accounting Course , plus
3) Gaining experience by obtaining a job in doing both chores under the supervision of a qualified accountant.

An added advantage is to learn EXCEL especially for the Payroll System.
Try and devise a payroll system on spreadsheets if the number of employees is say less than 30.

Yes, I have to agree that it really is a lot to ask. For instance, there are entire classes on payroll and then you wouldn't really learn everything. "Preparing" a general ledger is easy, so I'm assuming you mean something else, like everything about how to journalize, etc. and there isn't any one step-by-step guide to doing that -- there's a lot of rules, interpretation, and outright experience.

Is this for a real job, as opposed to school?

You're certainly welcome to ask specific questions about certain issues you're not sure how to handle.

Look . I am new in accounts but I just understand that if I have cash or something like tangible assets than its our CREDIT but if we withdral any thng than its DEBIT...
