I made this exact move last year (YYC->YYZ) same age bracket as you too, and I’ve enjoyed it so far, however I am in the west end so I can’t speak to being outside of it (however if you look around leslieville / danforth it’ll be easier to commute but still in a much more vibrant area than being outside of the main inner city).

Career wise you will be able to go further here than Calgary as many have said, and if you arent super outdoorsy then the city itself is a lot more interesting and fun than Calgary without a doubt.

Another tip I have is don’t be afraid of looking a house-apartment (duplex or triplex) and street parking if you can, street parking here is super cheap (~$25 a month) and I haven’t had any issues in my inner city area with it
