Currently: cap gains tax is 50% of the gain.

Based on the marginal combined income tax rate of fed and provincial.

so for example: 0-45k (cad) income - 20.03% is taxed.

Say I make $1million. cap gain. 50% of that is taxed (500k)

If I fall into the lowest income bracket of 20.03% I would need to pay

500k x 20.03% = $100,150 in Cap gains tax.

So 10% of the total gain...lol

foot note: they changed this a number of years back which was 75%
