Yes I think it may be unusual. The "Must leave Canada by [date]" is usual. They always say that. Case type 10 is a visitor permit; nothing unusual there. The "Must furnish proof compliance on 17 Nov 2011 at Port of Exit" I haven't seen before. My partner was originally only given 3 months due to lack of ties to the U.S. and the fact that we hadn't sent the PR application (though we had it with us, 90% complete) and we hadn't even paid the fees due to a misunderstanding that we had to pay fees to Buffalo (not true for a spousal sponsorship).
The original permit had the following Remarks:
"Confirm departure from Canada - Return this document to CBSA on or before 02May2010.
Apply for extensions through Vegreville Alberta -
www.cic.gc.ca, visitor, extend my stay."
In our case, we just applied to Vegreville just before the 3 months were up and we never returned the document to anyone.
If you have an exclusion order, maybe you are obligated to go back without applying for an extension. You could always go back for just a couple of days, then try again hoping to come across a sympathetic border officer who is having a good day. I have read of people here who tried 2 or even 3 times before being let in. However -- if they get any wind that you are trying to violate your exclusion order, they may give you a 1 or even 2 year exclusion.
