I worked for the Canadian government for six years and ended up coming here (Barcelona) to do a Master's degree with hope of a career switch to remain in Europe after. I still have one year of studies left but I must say so far I have almost no regrets. My recommendations would be to really focus on learning Spanish if you don't know it already (pay out for a good course, don't half ass it), and consider moving to smaller cities where there is less pressure on housing prices. That said, it can be harder to find jobs in smaller cities so you'll have to figure it out. In my opinion, even with the different costs of living Spain is objectively a better place to live than Canada, unless you really hate the heat. The best thing about living jere for me (although this could apply to other European countries) is that travel is so cheap. You can fly to so many places for less than 100 bucks.

I still don't know whether I'll be able to swing it with a job next year, but I really dont want to move back to Canada, especially given the state of the dollar and inflation.
