In my opinion it's almost guaranteed to be rejected. It looks like you only came back to Canada because you got a letter asking you to prove you were here.
A Canadian PR shouldn't be something you collect like stamps on a card. As a PR sponsoring a spouse, you are required to be physically present in Canada. You cannot apply and then leave for a year thinking it will still be processed. Cases like this are why genuine applications take a year to process, keeping families apart.
Your agent was wrong, and you made a choice to leave Canada until you were called out on it.
