I suspect it's even higher than this:

"When the funding is billed only to those 18,329,587 Canadians who actually pay taxes every year, the cost is about $60 per payer."

After all, there are tricks available to married couples whereby the lower income earner can take on some of the taxable income of the higher income earner, and thereby pay taxes on revenue that s/he (it's usually the wife) hasn't actually earned. In other words, she's paying her husband's taxes because her income is so low, and the money to pay those taxes comes from the chief income earner in the family, of which there is only one.
