You may be asked to attach a tenant liability insurance certificate along with your signed lease usually sent via DocuSign.
You can go to sonnet.ca and answer a few questions to get your insurance online. Most of the answers for the form pertaining to your insurance request should be there in the lease. You can choose any insurer of your choice. The process takes a few minutes following which you can attach the policy certificate (as attached) to your DocuSign. The lease signing is complete once the document is attached.
You can also attach a general tenant liability insurance you previously hold once it is moved to your new address as per the lease document you are signing.
