Inter Pipeline Ltd. is a multinational petroleum (oil, natural gas and petrochemical products) transportation and infrastructure limited partnership that is ranked among North America's leading natural gas and NGL's extraction businesses (from its liquids (NGL's) counterpart).

[7] Soon after the millennium, the energy infrastructure business was divided into 4 segments: conventional oil pipelines, natural gas extraction, liquid storage and oilsands transportation.

[6] In 2010, other Canadian trusts/funds converted to corporation's but Inter Pipeline's board of directors decided against it citing costs, a lack of tax benefits, and the market response to other companies that converted.

These subsidiaries, apart from the Denmark and Sweden operations, were sold to Spanish company CLH in late 2020,[9] a bulk liquid storage business.

Within the next year it went public on the Toronto Stock Exchange listing under the symbol KPC.UN.
