yup and a day later I got my packet 4 so I'm thinking they liked it.  Thanks again for your input. Cheers
 

If by just the checklist you mean with the ds+160, passport bio page, and checklist then yes.
 
Good luck

Sorry if I missed this but when you submit your Packet 3 email to the consulate do you just need to send the checklist page or do you need to provide copies of all the documents you needed to gather?  It wasn't clear and if you don't need to provide the documents in the email then I assume that since the interview scheduling wait times (Especially in Canada) are longer then you can get the Packet 3 submitted while you gather your documents up? 
Thanks

Nope.  Some consulates don't use the "packet" system anymore and post everything online and make the process 100% applicant driven while others are very structured and control the process very tightly..
 
Some consulates want document submitted before the interview others want it everything hand carried and presented day off.  
 
Your best resources are your fellow Canadians.
