In theory you're required to take the minimum funds for one person ~$12,000. This has been deemed to be the bare minimum someone would need to survive for a year without working. Bare, bare minimum.
Take enough to get you a rental deposit ~$1000
First months rent ~$800
Food ~$500
Expenses ~$500
One more question:
Do I have to carry cash with me or can I take bank statement of last six months so that I can transfer the money after opening account in Canada
