I should have added as these links can be confusing. You first should look under inland application. Sponsorship it currently taking 38 days based on that website, but we (in the month of September) are seeing around 27 days on average. Then go to outland applications and go to applications for permanent residents, which varies a great deal depending on which country you are residing in. Click on "family class: partners and spouses" which will show you the current processing time for each country. This is on top of what you'll wait for your sponsorship application to be approved in Mississauga (assuming you're applying outland). Once your sponsorship application is approved then CIC will send it to your outland Canadian immigration office.
If you apply for permanent residency without the help of your spouse click on "skilled worker received after November 28 2008" and that will show you the current processing times.
On a personal note, I have had friends that have come over as skilled workers to Ontario and it took a minimum of 1 year and a maximum of 1.5 years. But this is in the last 10 years! Also, they were coming from the UK as farmers and a speech therapist.
Hope this helps.
