Canada could have as many as 15 side deals on a range of issues when it signs the final text of the Trans-Pacific Partnership, federal officials said Friday.
Those agreements, which will take the form of letters, won't be done in time for Ottawa's planned release of a preliminary TPP text in the coming days.
On Thursday, Trade Minister Ed Fast promised to release a provisional copy of the TPP trade agreement in the next few days.
"The final number of side letters is unclear at this time but we estimate it could be around 15," a senior government official, speaking on condition of anonymity, told The Canadian Press.
The official said that the exact number of side-deal letters would be known only when the final TPP text is ready for signatures.
The agreement between Canada and 11 other Pacific Rim countries has been billed as the largest trade deal in history.
"The purpose of a side letter is to clarify bilateral matters between two parties that do not affect the rights and obligations of the other TPP parties," the official said.
They would cover "a range of different issues, like a bilateral agreement," or could involve an exclusion "or a recognition of" a specific sector. "Countries can request those after the fact," the official said, adding that the countries can agree on the topics of side letters, and draft the actual texts later.
"It's the same way with the negotiating text. You agree to what the parameters are and then the actual drafting has to take place."
The official did not say which sectors and which countries would be covered by side letters, noting only that Mr. Fast said Thursday that one of them would be between Canada and Japan on processed and unprocessed forestry products.
Dairy and autos have also proven to be contentious issues for Canada during the TPP talks, which reached their conclusion Monday in Atlanta.
It was in July when it first emerged that timber had become a sticking point between Canada and Japan. Leaked Canadian government documents in the summer said Japan was pushing Canada to eliminate or modify the controls it imposes on B.C. log exports.
Similar to the protections in Canada's supply management system, the export of B.C. logs is heavily restricted by the federal and provincial governments, which drives up their cost to foreign buyers.
In a statement Friday, Mr. Fast's spokesman, Max Moncaster, said the TPP "fully protects Canada's export log regime at both the federal and provincial level."
He added: "In the spirit of promoting trade in forestry products, Canada and Japan have also agreed to a side letter that establishes a bilateral committee to discuss issues related to trade in forestry products."
Mr. Moncaster said Ottawa is working closely with B.C. on the issue.
The trade pact has become a major election issue as the marathon federal campaign grinds towards election day Oct. 19.
The Liberals and New Democrats have accused the Conservative government of negotiating in secrecy. While the Liberals say they want to wait and see the text before pronouncing on the TPP, the New Democrats say they will not be bound by the pact if they form a government.
