With your investment portfolio, you can invest in different plans. Some give you a tax benefit, like registered savings plans, others don’t, but they can offer you other benefits.
The decision to invest in certain registered plans is based on your personal and professional circumstances, and your goals. So it’s important to discuss these matters with your advisor to make the best choices.
If you are in business and incorporated, you will also want to consider saving in your corporation and the benefits you can derive from this.
