TORONTO/MEXICO CITY, June 9 (Reuters) - Tycoon Carlos Slim's building arm Ideal has tied up with two Canadian pension funds to invest in infrastructure assets in Mexico, the companies said in a joint statement on Thursday.

Ideal will hold a 51 percent stake in the partnership, which is called "Newco", while Canada Pension Plan Investment Board (CPPIB) and Ontario Teachers' Pension Plan, have committed C$1.35 billion ($1.06 billion).

CPPIB will hold a 29-percent stake in the partnership, with Ontario Teachers' owning 20 percent.

Ideal is contributing its 99-percent interest in the Arco Norte toll road, one of Mexico's biggest toll road concessions, to the new venture. The Slim-controlled venture also has interests in sectors such as water, energy and logistics.

"Arco Norte represents our first infrastructure investment in Mexico and enables us to invest in an established, modern toll road of significant size," said Cressida Hogg, Managing Director and Head of Infrastructure, CPPIB, in a statement.
