What is the difference between the statements of Justice Wilson and Justice Chouinard in the context of Divorce and Social Security?

The foregoing quotation from Madam Justice Wilson is similar to the statement of Mr. Justice Chouinard in Messier v. Delage (1983), 1983 CanLII 31 (SCC), 2 D.L.R. (4th) 1, [1983] 2 S.C.R. 401, 50 N.R. 16, which was made prior to the revisions of the Divorce Act in 1985. He states at p. 14: That does not mean that the obligation of support between ex-spouses should continue indefinitely when the marriage bond is dissolved, or that one spouse can continue to be a drag on the other indefinitely or acquire a lifetime pension as a result of the marriage, or to luxuriate in idleness at the expense of the other, to use the expressions one finds in some discussions of the subject. It also does not mean that a divorced person cannot remarry, or that his new obligations or new advantages as the case may be will not be taken into consideration.
