No, not at all. AC is running their entire fleet at 100% right now and doesn't have a single aircraft to spare right now due to the 787 delays. So when the quoted the trip, it was at a price that they felt made it worth their while to juggle the schedule. They understood the price was high and they understood the impact that was having on the event. SMD5 moving just means they can put the 321 on the transcon it was scheduled for.

They are still throwing an amazing event at YYZ and a great party that night (as any SMD3 flyer can attest to).

Edit: Also, AC has confirmed that flyer that choose to post the miles to AP will get any Elite bonus they are entitle to as well.
