Canada's federal government and its provinces have agreed they need emissions-cutting measures beyond the minimum price on carbon unveiled last week, and the government will announce those measures in the fall, a senior minister said on Sunday.

Speaking on the CTV broadcaster's "Question Period" politics talk show, Environment Minister Catherine McKenna said the measures may include regulating energy efficiency in housing.

Liberal Prime Minister Justin Trudeau took power last November promising to do more to protect the environment, and last Wednesday Parliament ratified the Paris agreement to curb climate-warming emissions.
