It seems that you want to know what documents to submit with your Canada temporary resident visa application. These are listed in the official document checklist published by Canada.
You should read the entire checklist, as it is a bit long to reproduce here. But it does mention (among other things) that you should submit:
Copies of bank statements covering the past three months. Any additional relevant documentation (employment letter, pay slips, proof of pension, business registration, investments, etc.)
Proof of Business if you are self-employed. Provide business registration, tax clearance certificates, trade certificates, license and financial documents, etc. (certified business bank account statement for past 6 months)
Proof of employment - letter from your current employer and pay slips (last 3 months). Employment letter dated within 2 months of the application indicating occupation, job description, position, salary, allowances, years of employment and authorized leave dates.
