Is There a Canadian Equivalent to the EFF?

javacowboy asks: "I'm a Canadian citizen who recently emailed the Electronic Frontier Foundation to ask about the tax-deductibility of donations to that organization. They replied telling me that they have no presence in Canada and that they can't issue a Canadian tax receipt. What I would like to know is if there is a similar organization in Canada, working towards the same goals, that I can donate to as well as writing off the donations on my tax form."
