On July 20, 1969, Neil Armstrong stepped off the ladder of the lunar module and into history: “That’s one small step for man, one giant leap for mankind.” (Armstrong long maintained he said “for a man” — the “a” was lost in transmission.)

That line came to mind on June 29, when Prime Minister Mark Carney announced that Heather Evans will become Canada’s next Commissioner of Revenue effective July 13 – fittingly, days before the moon landing’s 57th anniversary. Evans has led the Canadian Tax Foundation since 2016 and was previously national managing partner of tax for a Big Four professional services firm. I have known Heather from my years in Foundation leadership, including as its chair before her tenure, and hold her in high regard.

“Revenue Canada”, formerly a government department, was converted into the Canada Revenue Agency in 1999 – freed from Treasury Board’s grip and given its own board of management, precisely to import private-sector discipline. While the org chart changed, the instincts never did. Heather’s appointment is a first: every commissioner since its creation came from within government. She arrives directly from the private tax community. The Union of Taxation Employees is “cautiously optimistic”. So am I, though for different reasons.

The CRA has a vitally important – and very difficult – job administering the Income Tax Act and numerous other statutes. However, it administers the law. It does not write it. Within the commissioner’s administrative authority, though, lie meaningful small steps – and Canadians should insist they be real ones.

Real ones? We’ve just lived through the alternative. Last September, after Minister Champagne publicly declared the CRA’s service delays “unacceptable,” the agency launched a “100-Day Plan”. In late October, the Auditor General released a scathing report on the agency’s call centres, and the plan’s true origin became obvious: the government had the report in advance and was managing the damage. When day 100 arrived on December 11, the results were what I predicted: bureaucratic and political self-congratulation. The 100-Day Plan wasn’t one small step. It was a moonwalk – a performance of motion, with the root causes left exactly where they were.

To be fair, some argue the plan produced real improvements and was the kick in the pants the CRA needed. Perhaps. But practitioners have documented many of the CRA’s issues for years, with no meaningful response. If it took an Auditor General’s report – and a minister’s political need to get ahead of it – to finally administer the kick, that is not a defense of the plan. It is an indictment of the culture – one that responds to headlines, but not to Canadians and their advisors who deal with it daily.

Culture is where the new commissioner’s real small steps lie. Her first test arrives immediately: in February, the government announced that public servants must work onsite four days a week; the CRA will implement the change in late July, unevenly. That lands two weeks after Evans takes office, with the same “cautiously optimistic” union having filed unfair labour practice complaints. I encourage Heather to see this through. Tax – including its administration – is a craft best learned shoulder-to-shoulder, not transmitted through a screen.
