HALIFAX — Nova Scotia Premier Tim Houston has followed through on his promise to introduce a bill aimed at reducing interprovincial trade barriers, in an effort to boost the economy amid tariff threats by the U.S. president.

However, he said Tuesday, provisions in the bill would only be extended to provinces or territories that adopt similar legislation.

“It’s a common sense change that I think Canadians are expecting,” Houston told reporters after tabling the bill. “We are comfortable being the leader on this, but of course we need other provinces to follow and to co-operate.”
