Pigeon, J. (all concur) :—In 1963 and 1964 appellant, then known as Monarch Fine Foods Limited, was manufacturing margarine. By its petition of right it seeks to recover the sum of $355,412.48 paid under protest for sales tax in respect of the sale of this product between April 7, 1963 and February 8, 1964. The claim for exemption is based on the contention that because a substantial proportion, varying between 48% and 90%, of the oil used as the main component in the manufacture of this butter substitute was herring oil, it is to be considered as an edible product of fish within the meaning of the following item of Schedule III of the Excise Tax Act under the heading “Foodstuffs” :
“Fish and edible products thereof ;”
Cattanach, J. dismissed the petition saying :
In my view, in order to determine whether a particular product falls within an expression such as “Fish and edible products thereof;” resort must be had to the common understanding of such words when used in relation to articles of commerce. The question here is, therefore, whether, in the ordinary use of words, margarine may be fairly regarded as falling within the words, “Fish and edible products thereof;” or more specifically, applying such a test: is margarine a product of fish?
I do not think that, in common parlance, the words “product of fish” can be considered as comprehending margarine, even though it contains fish oil as one of its principal ingredients. Margarine is itself a well known article of commerce and is neither marketed, purchased, nor thought of by the consumer as a product of fish.
It seems to me that the fish from which oil has been extracted and which is used in the manufacture of margarine, which is by no means the sole ingredient of the end product, has become so obscured by the processes to which it and the oil thereof has been subjected and by the oil being intermingled with substantial amounts of other ingredients from other sources, the whole of which is again the subject of an extensive manufacturing process, that the resultant margarine cannot be considered as a product of fish, even though the fish oil content may make the margarine a fish oil margarine and the labels thereon disclose the fish oil content.
Counsel for the appellant pointed out that before reaching the above stated conclusion, the trial judge had made a finding ‘‘that any margarine 40% or over of the total oil content of which is fish oil is referred to in the trade as a fish or marine oil margarine’’. It must be noted however that this designation does not appear to be used in connection with retail sales. Fish or marine oil margarine is not sold to consumers as a fish product and is almost invariably sold with dairy products in the same way as vegetable oil margarine. A trade designation in such limited use cannot be considered as of substantial weight in ascertaining the proper description of the goods for the purposes with which we are concerned.
Reference was made to the decision of this Court in T'ownsend v. Northern Crown Bank (1914), 49 S.C.R. 394. In that case, the question was whether sawn lumber was a “product of the forest’’ within the meaning of Section 88 of the Bank Act. Duff, J. (as he then was) said (at p. 398) :
This is only one example of the class of cases in which the court being loath and refusing to attempt to draw an abstract line, finds itself compelled to decide whether a particular concrete case falls on one side or on the other side of the line which theoretically must be found somewhere within given limits. In this particular case I prefer to say that according to the common understanding the articles in question would fairly be comprised within the description “products of the forest”, and I think they are within the contemplation of the enactment we have to interpret.
In my view, the trial judge applying this test was fully justified in reaching the conclusion that according to the common understanding margarine was not a product of fish, even when in specialized trading circles a particular kind was known as fish oil margarine.
Furthermore, although in some cases fish oil was the main raw material, in other cases and for a very substantial quantity it was only approximately one half the main raw material, it being mixed with an equal or nearly equal quantity of vegetable oil. Also, it was shown that all the fish oil used was treated to remove any odour or colour identifying it with fish so that, for the consumer, the product would be undistinguishable from margarine made from vegetable oil only. Finally, the refined, bleached and deodorized oil was hydrogenated, a process altering its chemical nature to such extent that, as Dr. Sims said, it was ‘‘no longer a fish oil, but a derivative of fish oil”.
In his argument in support of the judgment of the Exchequer Court, counsel for the respondent made reference to the new Schedule III to the Excise Tax Act substituted for the former one by Section 8 of 14-15 Eliz. II, c. 40 (assented to July 11, 1966). One of the new items is the following:
20. Oleomargarine and margarine for consumption in the Province of Newfoundland.
It was contended that this amendment of the statute could be considered in construing the former text on the same basis as this Court did consider an amendment of a zoning by-law in construing its original provisions in Wilson v. Jones, [1968] S.C.R. 554. I must point out that the two situations are entirely different. In the Wilson case, the amending by-law had been adopted long before the application for the building permit sought to be enjoined. Therefore, the amending by-law was to be considered as making one enactment together with the original by-law. In the present case, however, the tax sought to be recovered was paid in 1963 and 1964 and the petition of right filed in March 1964, long before the amending statute was enacted. In the absence of any declaratory provisions, the 1966 statute cannot have any retrospective operation and the construction of the schedule as it stood at the material time can, in no way, be affected by the later amendment.
The appeal should be dismissed with costs.
