That feels like a disadvantage by design. In a different (and more fair) economy, investing in government bonds or a savings account in your local credit union would give you a better deal then leaving your money with a global hedge fund conglomerate which in turn invests your money into all sorts of unethical companies, including oil and weapons companies.
Your government is way more democratic then your hedge fund. And I would wager your are in a massive minority (perhaps among my hypothetical < 2% who would own stocks by choice in my hypothetical economy) if you desire your unused money to be spent by Canadian billionaires to further enrich them selves, instead of your government investing in infrastructure, health care, education, etc. or your local credit union lending it to somebody in your community buying their first house, or opening up a new business which you are likely to shop at.
Anywhere else you put money as an investment will barely match inflation.
