Yes, online will kits are legal in Canada. However, there are some things to keep in mind when using an online will kit.
First, make sure that the online will kit you are using is up to date. The law surrounding wills and estate planning changes from time to time, so you want to make sure that the will kit you are using is current.
Second, while online will kits can be a helpful tool, they are not a substitute for professional legal advice. If you have any questions about your will or estate planning in general, you should consult with a qualified lawyer.
Third, remember that your will is a very important document. It is recommended that you have your will witnessed and signed by two independent witnesses. Once your will is signed, be sure to keep it in a safe place where it can be easily accessed by your executor.
