While it was impossible to miss Canada’s 150th birthday celebrations from coast to coast, what you may not have known is that 2017 is also the 100th anniversary of the Income Tax Act. In 1917 Conservative Finance Minister Sir Thomas White introduced the bill to fund the First World War effort. Initially the act was (supposedly) going to be temporary, however it had no end date. White had asked the House of Commons to decide on whether or not to keep it after the war had ended. Obviously, they chose yes.
The original form had just 23 lines to fill out for a taxpayer. Seems quaint by today’s standards.
