Can a sponsor who has given an undertaking to provide financial support to a spouse under a sponsorship agreement ignore their obligation to do so?

[66] The Government of Canada, in requiring such stringent undertakings from sponsors, has taken into consideration the inherent difficulties that some persons experience in making the necessary adjustments in coming to a new country and becoming self-sufficient. The sponsorship agreement cannot be ignored since to do so would render it meaningless. It would be contrary to public policy to permit a person who has given an undertaking to provide support for a spouse to simply ignore the legal obligation to do so. See Achari v. Samy, supra, at paragraph [13].
