While neither the Bank Act nor the Criminal Code deal with the mutilation or defacement of bank notes, the Bank of Canada strongly objects to any mutilation or defacement of bank notes including simple markings similar to your example. All writing on notes limits their life. Such instances of mutilation and defacement carry a cost associated with them due to accelerated requirements for note replacement. Further, the mutilation and defacement of notes is not condoned as Canadian currency is a symbol and source of national pride.
Having said this, the bank note you possess remains legal tender and can be used in commercial transactions.
