Yes, but cost of living adjustments are compounded, so for a UK pilot retiring in Canada the difference in state pension benefits over time will easily be in the hundreds of thousands of dollars, especially now that we are living longer. And of course that amount doubles for married couples.
So although state pension may be just a part of a larger overall, losing that amount of money is still a significant penalty for simply retiring in Canada vs. retiring in many other countries (including the U.S.) where the freeze does not apply.
