Can I leave Canada while my PNP is being processed?

[PinkyKaty]

I am currently on a one year open work visa (no extensions), which will expire in around 3 weeks and is stated on the visa that i must leave Canada by that date.

I have applied for a BC PNP,  having just recieved the email stating they are processing the application but it may take upto 12 weeks to process.

Therefore I am guessing I will have to leave Canada until I hear whether the PNP was successful. I just wanted to check this with someone who may know if this is correct? And when entering Canada again, after *hopefully* I receive the paperwork what kind of visa would I receive? Would this allow me to work while applying for the PR.

Thanks Katy
