CALGARY - Kinder Morgan Canada is paying $1.5-million bonuses to two senior executives to ensure they stay with the company as its Trans Mountain pipeline system is sold to the federal government in a $4.5-billion sales agreement.

The company says it approved the payments to president Ian Anderson and David Safari, the vice-president overseeing the Trans Mountain pipeline expansion, to be paid in equal parts in July 2019 and July 2020.

The payments, outlined in a regulatory filing, are conditional on their continued employment through each date.

Kinder Morgan Canada says the arrangements are “consistent with industry practice” for a project and transaction of this size.

The filing is dated on the same day last week that Finance Minister Bill Morneau announced the deal to purchase the pipeline assets.

The government has said it is counting on the continued employment of key pipeline staff to ensure the estimated $7.4-billion project to triple capacity of the pipeline from Edmonton to Burnaby, B.C., is completed.

The filing also notes that the company has terminated and repaid a $5.5-billion revolving credit facility with the Royal Bank of Canada.

Ottawa is to provide loan guarantees for any money the company spends on the endeavour between now and when the pipeline's ownership changes.

Kinder Morgan is to ask shareholders to vote on the deal before the end of July. If shareholders approve the sale, the paperwork is to be completed sometime in August or September.

Construction is expected to be finished in about two and a half years.
