Here’s a great error fare, courtesy of flyfork: Roundtrip flights between Vancouver to Paris for $298 CAD, for travel on May 5th to 12th, bookable on Skypicker:

The fare is with Lufthansa and the $254 fare is no longer searchable. I did not try the other destination cities (Berlin, Rome, Venice) or other origin cities as mentioned on Flyfork’s post. Also keep in mind this is an error fare so it could be cancelled.
For mileage run considerations, this works out to 1.86 cpm, however be aware Miles and More is only valued at 1.4 cpm by The Points Guy.
