May 4 (Reuters) - Canada's Enbridge Inc (ENB.TO) said on Thursday it has reached a 7-1/2-year toll agreement with oil shippers for its Mainline crude pipeline system, one of North America's biggest, after scrapping earlier plans for long-term contracts.
The agreement means that, if approved, Enbridge would continue to ration space on a monthly basis.
Enbridge spent years trying to convince shippers and then the Canada Energy Regulator (CER) to sell space on the Mainline under long-term contracts.
Some Canadian oil producers objected, while companies with refineries were in favor of contracts.
The new agreement covers 70% of Mainline deliveries, with the remaining 30% covered by a pre-existing agreement.
