I might have overlooked this, but is there a place for entering alternative investments for asset classes such as artwork, collectible automobiles, wine etc?  Presumably would be based on appraised value.

Yes, you can add investments to any account (so you may want to create a non-registered account to hold these).

Add a CAD or USD investment as appropriate.

The type of the investment would be "Other", and you would enter a name for it, say "art".

Enter 1 share, its value (current appraised value), its book value (what you paid for it after the costs of buying it), and the Asset Type as "Alternative or other investment".

Enter an expected Capital appreciation growth rate (% per year).

The other rates probably don't apply.
