Francois-Philippe Champagne welcomed the breakthrough in a tweet as "big progress" and shared a statement saying his government had agreed to "a framework for a new Comprehensive and Progressive Trans Pacific Partnership" after holding out for strict labour and environmental clauses.
Those elements were thrown into jeopardy by America's sudden withdrawal from the deal earlier this year, which forced the remaining 11 countries involved in the pact to reconsider the merits of a deal suddenly shorn of access to the world's largest economy.
The Canadian statement said "there still are a number of issues that remain outstanding for Canada" but welcomed "a new agreement" with environmental and labour protections linked to freer markets.
Canada had dug in over those progressive clauses.
But they are much less attractive to countries like Vietnam, Malaysia, Chile and Peru now that the carrot of access to the huge US market has been pulled.
