In the other five provinces, the PST has been merged with the GST (i.e. the
Harmonized Sales Tax (HST) in New Brunswick, Nova Scotia, and Newfoundland), or
replaced with a value added tax (Quebec), or never existed (Alberta). Chart 11 shows that
if there were no PST on the purchase of capital goods, the METRs in Canada in 2010
would be approximately 5 percentage points lower.
Tax policy experts across the political spectrum are unanimous that the current
PST regime which taxes the purchase of new capital equipment is extremely bad policy,
perhaps unique in its incompetence among developed countries.
The effect of such a tax is to increase the price of capital relative to the price of
labour, giving firms less incentive to substitute capital for labour and hence leading to
slower growth in the capital-labour ratio or capital intensity. Since capital intensity
growth is a key driver of labour productivity, the latter suffers. If Canada were a labour
surplus country, there might be some justification for such a policy on the basis of
fostering employment, at least in the short to medium term.23 But with the unemployment
rate at around 6 per cent, Canada should be encouraging substitution of capital for labour.
Evidence of the positive effect of the removal of the PST on capital investment
comes from work by Michael Smart and Richard Bird (2006) and Smart (2007). They
find that the growth in investment per capita has been more rapid in the HST provinces
that do not tax capital inputs than in PST provinces that impose such a tax. In an
23 It is however not clear that the long-run health of an economy is promoted by subsidizing employment
and taxing capital goods.
