It was, perhaps, the quintessential political product placement: Stephen Harper, surrounded by smiling supporters sporting Home Hardware’s signature red shirts, in front of a placard emblazoned with the iconic double H logo, laying out his plan to make the home renovation tax credit permanent at the company’s fall trade show in St. Jacob’s, Ont. on Monday.

While it may be the most recent instance of a party leader unveiling — or promoting — a campaign pledge against a carefully chosen corporate backdrop, Harper is hardly the only one to turn a visit to a local business into a scene-setter for a policy announcement.

New Democrat Leader Tom Mulcair unveiled his plan to boost federal assistance for tourism at Niagara Helicopters, which bills itself as the area’s “only year-round aerial attraction.”

Meanwhile, Liberal Leader Justin Trudeau chose to make his pitch for a teacher-targeting tax credit at Oakville-based Spectrum Educational Supplies.

It’s also not a particularly new phenomenon — the image of a hairnet-clad Gilles Duceppe touring a Quebec cheese factory during the 1997 campaign will likely haunt the Bloc Quebecois leader for the rest of his political career.

What is new, however — at least relative to the campaigns of the 1990s and early 2000s — are the daily, and often twice daily, televised press conferences. During these, the leaders make their announcements and take questions from the press, all in front of a live audience, often made up, at least partially, by employees of the business hosting the event. (How many times have you seen a leader speak against a backdrop of hard hat and/or white-coat -wearing spectators?)

That, combined with steadily more aggressive branding by some hosts, makes the cooperation between the private and political sectors far more visible than it was in the past.

The rules barring businesses from meddling in politics are also far more stringent these days: corporate, union and association donations to parties or candidates are banned outright, whether as a monetary contribution or by providing goods or services that would otherwise cost money.

Given those restrictions, are these company-hosted appearances still legal?

Entirely so, according to Elections Canada: There’s no rule that would prohibit a company from offering itself up as a venue for a campaign announcement.

“While the treatment may differ based on the facts of a given situation, to date the provision of a forum to serve as a backdrop for a campaign announcement has not been considered a political contribution on the assumption that is has no commercial value,” Elections Canada spokesman John Enright told The Ottawa Citizen.

Even so, he noted that “any incremental costs incurred in providing the venue” would have to be covered by the party, or it could constitute a non-monetary contribution from an otherwise ineligible entity.

That could include special lighting, seating and other staging elements, as well as security and additional personnel, although in most cases, those would be provided by the tour itself, as it usually travels with an ample supply of lecterns, signage and placards.

At press time, none of the parties had responded to a query on whether they had ever picked up the tab for expenses emanating from an announcement, media availability or photo op on corporate property.

They also declined to provide any additional information on precisely how such events are arranged — namely, is it the company that approaches the company, or the other way around?

We can, however, draw some tentative conclusions from their respective leaders’ itineraries thus far — first and foremost of which would be that, for whatever reason, the Conservatives are far more likely to get (or solicit) an invite to drop in on a local company while criss-crossing the country.

An analysis of public events featuring all three leaders to date shows that Harper has made 22 appearances using a local business as a scene-setter — very nearly twice the number of appearances by the other two leaders (6 each) combined — at a wide range of venues, from a potato-washing plant on Prince Edward Island to the Seaspan shipyards in Vancouver.

Meanwhile, Mulcair and Trudeau seem more likely to show up at high tech shops like London-based Sciencetech Inc., which specializes in optical spectroscopy, or plasma processors Pyrogenesis Canada in Toronto.

Finally, all three leaders have shown their support for Canada’s air industry — from helicopter tours out of Whitehorse to plane servicing and charters in Mississauga.

Here’s the complete list — or, at least, as complete as it was possible to cobble together from the available data, so if we’ve missed anything, drop me a line (komalley@ottawacitizen.com) and I’ll add it.

Note: After much — or, at least, some — consideration, I decided not to include photo ops and meet-and-greets at local restaurants, coffee shops, pubs or similar establishments, as those are generally more informal events that don’t require the proprietor and/or staff to play an active role (or, indeed, any role at all).
