If for some reason Air Canada doesn't want to reimburse you for the free baggage you were entitled to you have a few options. You can complain to the CTA and wait a couple of years for them to get back. If you are based in BC your best bet may actually be the BC Civil Resolution Tribunal which provides a fast and cost effective way to pursue the airline for breaches of contract like this.
The most direct path might be to call the credit card company and simply dispute the charge saying you were double charged for the same purchase. The drawback here is that whilst you may get your money back, the airline (Korean Air) may put you on a blacklist. So whilst it is a bit of a more pain to go through the formal method it is the most legally sound.

Actually, under the Canadian APPR the airline is only required to rebook the customer on the next available flight. There is no requirement to offer to cover the customers baggage.
Should the customer not want to pay the baggage fee, they should decline the initial rebooking and seek a new rebooking from the airline onto another itinerary that includes baggage. It might also be possible for the initial airline to rebook on the same flights but in a higher economy class fare that would include checked baggage.
If you have travel insurance or travel insurance included as a credit card perk you could claim it as an expense through there. Otherwise, the charge is on you.
Disputing a charge with your credit card company likely won't prove to be successful as the charge was legitimate from Korean Air. They charged you for a service to check your bags. You received the service. It's not like someone stole your card and went and bought a ticket with Korean Air without your knowledge.
