It's fine. We use geothermal heat pumps with the lines buried below the frost line. (6-8 feet below the surface.) I know quite a few houses and even a few factories (30,000 square feet+) that use them in temps that drop well below -30c to -40c without any issues.

The initial setup cost is a fair bit more because of having to bury the lines, but after that they're fine.
