Chairman David Argyle, who will remain as majority owner of the Canada-based Championship club, has also revealed they failed to meet payments to its players in time for Christmas but insists they will be paid in full this week.
"A major new investment in the team has been our key priority through the last three months," said Argyle.
"In prioritising the long-term, we unfortunately caused some short-term pain as our December payroll for players was delayed.
"We are obviously not happy that we fell short of the values and standards we hold ourselves to as an organisation."
Argyle, an Australian mining tycoon who has bank-rolled Toronto in its first two seasons, says the cash injection, which will come from the launch of Wolfpack-branded isotonic and alcoholic drinks and a wellness product, will ensure the club's long-term sustainability.
Toronto, who gained promotion from League One in its first season , fell just short of reaching Super League in 2018, losing the Million Pound Game to London Broncos, but are favourites under new coach Brian McDermott to top the 2019 Championship which gets under way in a month's time.
"This injection of cash prepares us for the next phase of our journey,"
"Having been financed exclusively by private investment to date, our refinancing now means we have a rigorous and sustainable business model to push into 2019 and beyond.
"We are very grateful to our new investment partners and look forward to working together to grow our respective organisations."
The new investment is from Canadian companies who will use the Wolfpack's growing platform to expand into the UK and the rest of the world.
Toronto drew an average crowd of 6,565 to the Lamport Stadium in 2018 and say their TV broadcast partnerships reached 150 million homes across 19 countries in their first two years.
The club also recently bought a minority stake in League One club London Skolars.
