Any advice will help and be much appreciated (Montréal)

Hello everyone,
I am from Romania, I have been living in Spain for 7 years (there I decided and applied for Montreal as in Spain is difficult to find a good job) then in Protected content moved to UK- Manchester so the last 2 yrs I work in Retail, and feel like i could improve in future by studying here in UK. Now I have the Visa (I should be in Canada by July) and I am trying to make the best decision. The question is: Does it worth it to move to Canada? In which way is Canada better then UK? Any British moved to Montreal can give me an Advice?Or any Canadian moved to UK? Or anyone else who can give me an idea is welcome.
Many thanks
Regards
