The most important part of estate planning is ensuring that you have a valid, up-to-date will. If you die without a will, the government will distribute your estate according to provincial law. The best and safest way to create a will is to hire a lawyer who is familiar with estate and family law for the province where you reside. There are many "do-it-yourself" will packages, but these can leave details open to legal interpretation. The cost of getting a proper will done is minor in comparison to the expenses that can be incurred when assets are not adequately protected. Your will is not a one-time document; it should be revisited every three to five years and at major life events such as marriage, separation, divorce, and the birth of a child to determine if it is still in keeping with your wishes.
