Corporate-based money market account. Will generate about 30 bps (ballpark) more than what you'd get in a traditional money market fund. Canadian T-bills from 1 month to 1 year are roughly at a 2.6% yield; add a small fee for running the money market fund, and your yield is about 2.5%.
With ZST, you'll get something like 2.8-2.9%. Very safe, very high quality corporate credits in Canada. Great vehicle for a number of years to get an enhanced yield on your cash savings.
Yes, it's a very safe vehicle. It's a good way to extract a bit more yield than from just a traditional money market account.
The challenge is that it's fully taxable. Instead you may want to look at some preferred securities, which give you a bit higher yield (bit more risk, but better tax treatment). Investors will need to do their own research on individual ETFs. Whatever the choice, it can be combined with ZST for safety of principal.
