Should Canada relax restrictions on foreign buyers and investment in real estate while impacted by Tariffs?

Tariff uncertainty has stalled already tepid activity in the pre-sales market, reigniting talk about the pros and cons of foreign buyer rules. The Bank of Canada rate hold last week continues to stall an aleady slow market.  
Before the foreign buyer ban in Canada, foreign buyers generally accounted for a small percentage of home purchases, typically ranging from 1% to 5% in major cities like Vancouver and Toronto. In some regions, this percentage may have been even lower.  Is this a good time to revisit the rule?
