Couple of other considerations .....
What are you going to 'do' after you've sold the business/retired?
Most folks would look at partnerships (spread the load AND the financial risk), funded from an RRSP (check the rules) in a series of tranches. It's really something to 'do', with the intent over time of paying yourself a cumulative salary > the cost of your purchase - and letting the RRSP absorb the business risk. Lots of possibilities, so talk with your adviser.
Look at physical assets.
Most would 'buy up' (bigger/pricier house) via the primary residence, and sell 3-5 years later to capture a tax free gain (maybe); ideally the gain covers the cost of 're-decorating', you net out about even, and your 'significant other' ALSO has something to do. Variations on the same theme are being a landlord, or hotelier; and using the assets 'creatively' (talk to adviser).
Look at philanthropy.
Fund your own 'foundation' via an annual charitable donation, and use the proceeds to physically go to 'where ever' and do good works. All your costs are paid for by the charity, the government gives you a tax deduction to help the process along, and you get the satisfaction of having done something useful. The 'wealth exists to be used' approach.
Different strokes.
