493. The sole fact that the City of Laval has not levied the special tax imposed by a by-law adopted under section 33, 36, 37, 38, 42 or 42a of the Charter of the City of Laval (1965, 1st session, c. 89) or under section 27 of chapter 96 of the statutes of 1968, or contemplated in those sections, is not a cause of illegality.
The repayment of the loans contemplated in the sections mentioned in the first paragraph is, whether or not the council has availed itself of those sections, a charge, from the municipal fiscal period 1980, on the aggregate of the taxable immoveables of the city of Laval, on the basis of their values entered on the assessment roll in force each year.
The second paragraph does not apply to loans the repayment of which is financed by a tax based on the frontage of the taxable real estate under the by-laws referred to in the first paragraph.
