Is There a Tax Treaty Between Usa and Canada?

How are Canadian Social Security benefits taxed in the US?
XVIII (5) (b)) Thus, a maximum of 85% of Canadian social security paid to a U.S. resident may be subject to U.S. taxes. However, if Canadian social security is amended to make benefits means-tested at the source and not subject to tax, the benefits will not be subject to U.S. tax (Canadian Protocol Treas. Tech. Explanation Pg. 4.).
