Which investor is most likely to have their entire investment covered by CDIC?

The investor who is most likely to have their entire investment covered by the Canada Deposit Insurance Corporation (CDIC) is the one who invested in a market-linked Guaranteed Investment Certificate (GIC).

CDIC insures eligible deposits made in Canadian currency at member institutions, covering products such as GICs, up to a certain limit. The coverage includes traditional GICs that are held within the insurer's limits, typically up to $100,000 per depositor, per institution, in a single insurance category.

In this case, the market-linked GIC falls under the eligible category where investments in such products are insured by CDIC as long as they meet the requirements. This means that if Alex invested in a market-linked GIC, the full amount up to the insured limit would be covered by CDIC. Other investors, such as Mark, Martha, and Patrick, either invested amounts exceeding the CDIC insurance limit or in currencies that are not protected because they are outside the jurisdiction of CDIC, which further supports the coverage of Alex's investment being the most secure under this insurance scheme.
