CRA defines residency status in a different way, and it has nothing to do with your landing date. Temporary residents should also file tax return if they are deemed to be a resident per CRA definition. http://www.cra-arc.gc.ca/tx/nnrsdnts/cmmn/rsdncy-eng.html
If you don't want to become a resident per CRA definition, don't apply for any benefit, don't open any bank account, don't buy any properties, don't apply for OHIP... cut off all the economical ties with Canada.
It is your sole responsibility to determine when you become a resident per CRA definition. The date you put on your first tax return file should be able to go through all scrutiny. You can not put a random date, which you can not validate when CRA audits your tax return. All documents pertaining to tax return should be kept in a safe place for seven years in case CRA asks for them.
