First thing, make sure to apply for your extension. If your passport gets stamped with a date, apply before that date. If its not given a date, at the five month mark. If you're denied and asked to leave, please do so on time. It will look better for next.
It's okay to change your mind and decide to remain "after" you enter Canada. My husband (then boyfriend) asked me to remain, so I could truthfully tell CIC this was the case. This is a bit of a gray area... Don't volunteer information and don't tell them you intend to stay. When/if they ask if you'll leave at the end, say yes. If you aren't given an extension you will leave ( to reset status, details lol).
