That Tank is a fish only with live rock settup and allot of the equipment may not work well for a full mixed reef.
you will need :
a good skimmer $600 used to $3000
A halide canopy to fit (4) 400 watt metal halides with the larger luminarc reflectors made to fit on top and open up for access and or cooling/Fans. The lighting retrofit will run (this is an educated guess) $850 - 1500 This does not count making the canopy out of wood I assume living where you are you can build one

For the Summer You May need a Chiller ( Thing's die if they get too hot and Need Halide lighting!) You need to try to keep the Temperature from Varying more than a few Degrees for the Best health of the Corals-- A Chiller for this size a tank $1200( a guess)
For water flow it gets down to the best at a premium and Several other theories.
The best would be IMO (6) Eco Tech Marine Vor Tech MP40W Pumps $2400

Other best bets are a closed loop Wich needs a Large pump and without other devices will not alternate the flow If you add a Motorized Ball Valve then You are set and it is as good as the above and quite possably cheaper But you need to have plumbing inside the tank.
You should Have a Large Tank for a Sump That 200 Gallon tank would be perfect.
If you are keeping Corals Eventually you will need a Calcium and or Kalkwasser Reactor- You could build them yourself and Buy all the Necessary Parts Figure on $300-$3000
Depending on Allot of Different Factors But you EVENTUALLY will need this IF you decide to Raise SPS or LPS corals . If you just keep Zoo's and Leathers Then maybe not !
From what a Biologist told me you really don't need that much live rock and it is overrated as the plumbing in our systems houses allot of bacteria But That is his opinion . A mere 300 Lbs Of live rock In canada Might be hard to find I would Not get what he has in that tank picture I would Order it if necessary And Figure Even with a BIG Discount That could Easily Run $1000 But varies ALLOT over time and depending on the type etc. Lace rock is just fine and cheaper Just get Large Porus Pieces.
Add at least $100 Per month to your electricity bill .
You might want to consider a De Humidifier For the room it is in- A fairly big one.
An Auto top off for keeping the water lavel constant it Critical and less than $200 Don't skimp on these listed items as these are Just the basics
A Controller Is Not mandatory But Is a good Idea You Will Spend $150-$1000 On This .
Any 1 coral from say Dr Foster and smith Delivered live ( If they deliver to canada?)
Will Run $120 + $60 for shipping For a 4" Colony And Anything smaller in that tank you won't much see From a distance.
Is There a club in your area or other's to trade with or a store?
If not everything you need for supplies will have to be shipped!
So I guess If It Was Me I would Say Can You Afford $10,000 + To Put into to it BEFORE you even add fish or corals And Then $250 A month for Salt/ Light's/Electricity ?
This is what A FULL BLOWN reef Will Most Likely CONSERVATIVELY run you.You Can do it cheaper But eventually You Will need or Want everthing Listed and More I have not.
Also Most people Don't leave there house for days at a time because they want to be there to fix any problem that arises ( and there are allot of things that can go wrong).
If you buy an expensive controller it will even e-mail you whats wrong with your tank ( assuming you program it correctly and Have allot of monitoring features)
Not to scare you But I feel you wanted advice And this is some of what a FULL BLOWN REEF NEEDS.
Most People Try to GET BY and then GIVE UP about 6-18 Month's Down the road because They NEVER got all the Automation Equipment and Had allot of livestock Die.
