Your marginal tax rate is the rate you pay on each additional dollar of income. It's different from your effective (average) tax rate, which is your total tax divided by total income. If your marginal rate is 43%, earning an extra $1,000 costs you $430 in combined tax.
RRSP contributions are deducted at your marginal rate. If you're in the 43% marginal bracket and contribute $100 to your RRSP, you get a $4,300 tax refund. When you withdraw in retirement at a lower rate (say 25%), you've saved the difference. This is the core tax arbitrage of RRSPs.
Alberta residents at $100,000 face only a 30.5% marginal rate — versus 43.4% in Ontario and 40.7% in BC. That's a $13,000 annual difference at $100,000 income. The Alberta advantage is most pronounced between $100,000 and $148,000 where other provinces are in higher brackets but Alberta remains at 10% provincial rate.
Quebec consistently has the highest marginal rates in Canada. However, Quebec residents receive more government services: subsidized $10/day childcare (recently increased), cheaper university tuition, and broader social programs. The higher taxes fund these directly. Whether the trade-off is worth it depends on your family situation.
Your marginal rate determines whether non-registered investing, RRSP, or TFSA is most advantageous. At marginal rates above 40%, RRSP contributions are highly efficient. TFSAs are always beneficial regardless of rate. Capital gains are taxed at 50% inclusion, so the effective marginal rate on capital gains is about half your regular marginal rate.
