I've decided to revisit this post from last year. The background context is the Conservative government's 'starve the beast' agenda - documented by me here and here, by Livio here and by Paul Wells in his excellent new book. The Conservatives have made two significant tax cuts during their time in office. The GST rate was reduced from 7% to 5%, and the corporate income tax (CIT) rate continued the downward trend begun during the Chrétien-Martin years: the statutory rate went from from 21% (22.1% with the surtax) in 2006 to 15% (no surtax) now. So far, the only tax cut anyone seems to want to rescind is the CIT. The NDP has already said as much, and the Liberals may or may not follow suit as they did in 2011.
