I've seen quite a few posts and articles recently citing the Canadian Taxpayer Federation. I want to provide some information about who the CTF is, according to Wikipedia:

The Canadian Taxpayers Federation (CTF; French: Fédération canadienne des contribuables) is a federally incorporated, non-profit organization in Canada. The Federation describe as a populist "citizens advocacy group" but critics accuse it to be an astroturf organization.

They have 5 members, or board of directors, who decide the direction of the organization. Many of their directors go on to or come from conservative, separatist, or far-right political parties. A number have gone on to be editors for right wing media such as the Toronto Sun and the National Post.

So when they say "x% of Canadians disagree with [liberal policy], just keep in mind who their respondents are and what the organizations here to do.
