Final answer:
TELUS starting its own Canadian bank is an example of diversification, where the company is expanding into a new market or industry, separate from its original telecommunications business.
Step-by-step explanation:
If TELUS, a telecommunications company, starts its own Canadian bank, this is an example of diversification. Diversification is a business strategy where a company enters into a new market or industry, which is different from the company's regular business. By starting a bank, TELUS would be diversifying away from its core business of telecommunications and into financial services. This can be seen as a way to reduce risk and capitalize on new market opportunities.
