Same time, same package, sent to CPC-Mississauga. They will send the OWP application to Vegreville AB to process it.
Being married is a slightly different situation. Provide some proof (pics, etc), but I think it can be a little easier on things like skype calls or texts (you are living together, that is way stronger than a skype call). Do not think that you don't have to provide any proof, but it can be a little more lax. When I submitted, we had been married for 8 months (June 2015), and I was just looking for the right time for us. Each application is different.
