According to Magren Holdings Ltd. v. Canada (2024 FCA 202, at paragraph 156), "a sham exists when acts are done or documents are executed with the intention of giving the appearance of creating legal rights and obligations that differ from the actual legal rights and obligations that the participants intend to create."

The CRA and the Crown have been accused by practitioners of inappropriately treating sham as an alternative argument to GAAR in support of reassessments. A statistical analysis sheds light on four key questions in this regard: (1) Is sham a successful legal argument for the Crown? (We measure success by the Crown by the outcome at the final stage of the appeal process, if any.) (2) Is sham a successful argument when combined with GAAR? (3) How commonly is sham raised alongside GAAR (and vice versa)? (4) Is sham argued more often in certain types of cases?

Canadian Abridgement Digests classifies judicial decisions according to the issues addressed in each case. We used this source to identify 99 cases in which sham, GAAR, or both sham and GAAR were raised as issues. For this analysis, we examined the period 1988 to the present (the period during which GAAR has existed). A supplementary table (which includes certain explanatory notes) provides the underlying data. We examine two overlapping subgroups of the 99 cases—one relating predominantly to sham and one relating predominantly to GAAR.

To answer the first question—"Is sham a successful legal argument?"—we examined the 27 cases in which sham is one of the issues. In the accompanying table, we show that the success rate for the Crown is 33 percent ([7 + 2]/[16 + 11]) in arguing sham. However, this aggregate figure conceals an important distinction that answers the second question: where both GAAR and sham are raised, the Crown's success rate in arguing sham is low (18 percent); in contrast, where the Crown argues sham alone, the success rate is higher (44 percent).

Thus, the courts seem to be more open to accepting sham where GAAR is not also raised. Perhaps the courts view the sham-GAAR double argument as a last-ditch strategy that the Crown uses when it does not have a truly persuasive argument to make.

The third question asks how commonly sham is raised alongside GAAR (and vice versa). For this, we examine a second subgroup of the 99 cases: the 82 cases in which at least one of the issues is GAAR. We find that sham was raised infrequently (in 12 percent of the cases, calculated as 10/82). This is perhaps less often than practitioners would expect. In contrast, in cases involving sham as one of the arguments, it was common for the Crown to also raise GAAR (in 41 percent of the cases, calculated as 11/27).

The last question is whether the Crown's assertion of sham in the 27 sham cases is concentrated in cases dealing with certain subjects (loss trading, surplus stripping, manipulation of tax attributes, etc.). Each case is assigned to a single category. The graph shows that there did not appear to be any discernible pattern, although sham appeared somewhat more frequently in cases dealing with impugned partnerships and losses.
