The federal government is spending half a billion dollars to commemorate the 150th anniversary of Confederation – with everything from a cross-country RV tour to a Parliament Hill extravaganza marking the occasion.

The largest share of the money – $300-million – is being delivered by regional development agencies through the Canada 150 Community Infrastructure Program. The previous Conservative government created that fund to fix up public facilities and for community infrastructure, culture and recreation. It was given a $150-million budget shortly before the 2015 election.

At the time, Liberal MPs called the program a "slush fund" because cheques were quickly handed out before the fall campaign. However, the Trudeau government's first budget doubled the program's size. Recipients are required to post black-and-white signs that tout the federal contributions in their facilities until March 31, 2018.

The expenses include:

Much of the planning of the 150th celebrations began under Stephen Harper's government, but the Liberals quickly put their own stamp on it. The Conservatives wanted celebrations to emphasize Canada as "strong, proud and free," while the Liberals redrew public servants' marching orders to focus on diversity, reconciliation with indigenous peoples, the environment and youth.

Of the Canada 150 money being handled by Canadian Heritage, $20-million is for major events. Of that, $5-million was spent on New Year's Eve 2016 celebrations across the country, a department spokesperson said, with $2.5-million alone used for a Parliament Hill party headlined by Call Me Maybe hitmaker Carly Rae Jepsen.

Parks Canada is offering free admission to all domestic and international visitors at national parks and historic sites this year. The department says it has received 1.9 million orders for free passes in the past month. This initiative, plus free admission for youth under the age of 18 starting in 2018, is expected to cost $83.3-million over five years.

The federal government spent $100-million for centennial commemorations in 1967 (about $779-million in today's dollars), which included the construction of buildings such as the National Arts Centre in Ottawa.
