In the 1950s, the dynamic duo of PM Louis St. Laurent and the "minister of everything" corporately connected CD Howe successfully weaned the big business sector away from the Conservatives to the Liberals.

As a result, in all or almost all elections since 1953 the Liberals grabbed a significantly larger share of the major corporations' donations that the Conservatives.

During the Harper era. the Conservatives earned more donations than the Liberals by a wide margin.   However, these were predominantly small donations ($100 or less) from tens of thousands of individual supporters.  The Liberals continued to enjoy their large lead in terms of average donation and this was from the corporate community like Bombardier who know which party is available for rent.

So sorry the facts discredit your scenario which is over 60 years out of date.
