A job offer in Canada is not enough. The employer needs to apply for and receive an LMIA for you to be able to apply for a work permit. Employers must meet strict requirements to get LMIAs, so it is very difficult to find this.
From your previous posts, you seem to be trying any way possible to come to Canada but lack a complete understanding of the Canadian immigration system. You also mention a criminal background.
You need to either actually do some research on this process yourself or hire someone to help you.
