Well let me say Welcome to Canada
Which part of the country are you aiming for? I live in Laval, just north of montreal, and bought a 3 bedroom house for less then 180,000. I'm moving in in 2 weeks!!!
as far as tanks go, they are much more expensive here then in the states. Everything cost about twice as much. Same goes for computers.
Now what I'm wondering is if the 5500$ covers the whole setup, tank, stand, light, filters, heaters, gravel, decorations.... if it does, then that's a decent price. I'm sure you can find it cheaper by shopping around but there's no way you can order that online in Canada unfortunetaly. Custom tanks are very expensive as the hobby is not very popular over here
I bought a 90 gallon setup and it cost almost 1500$ everything included.
I'm sure if you stick with a more standard size, like 225 gallon (6x2x2) tank, it would be much much cheaper.
