You don’t need to signup to the class action lawsuit anymore, because mazda issued the extended warranty. Typically these warranties extend to Canada as well, but not always. Remember Canada has a different powertrain warranty than the U.S. (unlimited km vs 60,000 miles).
The only way to know would be to ask the dealer directly or Mazda Canada. I would bring them this letter and this tsb and ask if there is a similar warranty extension in Canada.

If it isn’t i would:
- make sure that the 2021 still has a fair amount of powertrain warranty left. The symptoms are easy to spot (oil consumption) but you will need to drive it for a while to observe the oil consumption trend and for the dealer to diagnose it, because they will likely want to fill it themselves first and then measure the oil level later, and that takes time and mileage added to do.
-check with another mazda dealer if the work has already been done. I often call my local dealer to ask for the maintenance history of used Mazda that other dealers are selling. They are usually pretty open about providing the info and it is often ( but not always) recorded in the mazda central database. If the work has already been done then that should be ok. If not then it is not guaranteed to be an issue, but it is a roll of the dice. You know enough of these had problems for a class action lawsuit to be successful.
My recommendation would be that if you can afford to wait, wait for a better vehicle to show up on the market, or extend your search radius. To get a good deal on the used market you have to be patient and to be willing to travel to go get the deal. The used car market in my city isn’t great (almost always overpriced), for my last three used cars i have travelled to Montreal and Toronto to get them. Way more availability and better prices. Obviously it depends how close you are to bigger market, but if you get the option to drive a few hours to get a better car it is worth it.
For the 2022, i would only consider it if it was massively discounted. Keep in mind that a car with that history will also be really hard for you to resell, and you need to trust that all the repairs have been well done. There can be great deals to be had on rebuilt vehicles, but they need to be deals. If it is close to the 2021 in price, i don’t think i would go for it.
Also can you get the 2021 to be a mazda certified vehicles ? I believe that would extend the entire powertrain warranty to 7 years. I would be comfortable with a 2021 CPO with that kind of warranty.
