Im not forcing any Ukrainian to fight. They can surrender anytime they want
Russia can surrender or withdraw any time they want also. The difference is if Russia withdraws, they are left whole (territorially) and can continue to exist.
If Ukraine surrenders, they cease to exist as a country, their population will become persecuted, tortured and killed, enslaved with their children brainwashed, and conscripted into the Russian army to fight the next Russian war - be it Moldova or the Suwałki Gap or Georgia or...... Russia will acquire a huge amount of petrocarbon and other resources and be in an even better strategic position to force their will upon Europe.
You say you are 40 years too old. That would make you about 100 since even in Canada, let alone Ukraine, you can be in the military until 60 (or longer if highly skilled or ranked). So I doubt you are actually too old. I read that as you would be unwilling to fight against Russia if NATO and Canada became involved. To each his own I guess.
And that does not even consider the geopolitical message it sends to "the Axis of Resistance" (their term, not mine). China, Iran, Venezuela, Russia, Cuba, Syria, Lebanon or any of the other 67 autocracies/dictatorships around the world who might decide that the global 'North' (aka western democracies) has no will or power to prevent or punish them from declaring war and invading their neighbors in a territorial, water/oil/resource grab.
The only marginally safe countries will be those that possess a nuclear deterrent. Many many more countries will immediately start to develop their own nuclear defense capability puttng the entire globe, and humankind, at more risk.
I assume from your presence here that you have some sort of interest or experience with military, Canadian or otherwise. So to promote a let 'Russia win' position says to me you are either incredibly poorly informed, a troll, or a pro Russian sympathiser/agent.
Giving you the benefit of the doubt, I suggest you broaden your horizons and apparently parochial view of this conflict and think of the world your offspring and relatives would have to live in should your preferred outcome take place.
