Definitely no 5-7% discounts in Ontario. Expect $0 to maybe $1,500 if you're a regular customer of your dealership of choice. The OMVIC fee is waived by downtown and their $299 admin is probably the lowest (or was). Winter mats or an oil change are the usual "discounts".
Yep, that about sums it up. I purchased 3 Porsches from my dealer and service 5 Porsches there and I got $500 off my Macan back in late 2014. Hard to tell really since it could have just been an adjustment on my trade (2014 Cayman S). Things may have changed now that the supply is better.
