Province of Ontario has long been a hotbed of Canadian Digital Signage activity. It’s home to many well-known digital signage companies including (and definitely not limited to) CognoVision , Adflow , Omnivex , OneStop  and Capital Networks .
If you are one of these companies, or developing your own solution set to revolutionize the digital signage market, make sure you maximize all sources of provincial and private funding available to Ontario businesses.
To help navigate sources of available funding see this great resource for sources of provincial and private funding available for technology companies in Ontario  compiled by MaRS . Many of these grants and funds are applicable to companies in the Digital Signage Sector.
I would further encourage any growing technology company in Toronto or Ontario to get involved in MaRS community. It’s a great organization dedicated to promoting growth of technology and innovation in Canada.
