The ban on non-essential crossings of the U-S-Canada border is being loosened.
Prime Minister Justin Trudeau says it is aimed at allowing some families to reunite.
But Trudeau says the rules still require anyone entering the country to self-isolate for two weeks -- and he warns against breaking that rule.
The border with the United States has been closed since March, except for goods and certain categories of essential workers.
Immigration Minister Marco Mendicino says there are conditions travellers must meet to get into Canada, including being married or attached common-law to a Canadian.
The change does not apply to non-citizen family members of Canadians living in other countries outside the U-S.
