The story
Ontario Teachers' was established on January 1, 1990. Until then, Ontario teachers' pensions had been sponsored solely by the Ontario government. Assets of the plan had been invested in government bonds only. Currently, it invests globally in fixed income, public and private equity markets, real estate, infrastructure, natural resources, credit and venture capital through Teachers' Venture Growth (TVG).
