What to choose staying in my country or move to Canada?

I am from Europe and I have lived before in italy and UK. So I know that moving and starting life in new place is not so easy. When finaly i started feeling that everything is its place with job that I like, have here also house, apartament land and i had big plans with my land. The only thing that i live in country if war starts in Europe it would start from here. Because we have border with Russia. So lately they been scarying people there might be war later or sooner. So because of that i applied for a work experience in Canada , plus i did in the past dreamed of living there. So i got message that i can get visa. I am confussed because at the same time i do want to go, but i am 34 and i feel its to late to start life there and same time i feel i wanna stay because of my mother, grandmother they are not getting younger plus everything i have here and my plans. I am so confussed what should i do? I am fear i wouldn't destroy my life. Canada now also not in the best economic situation.
