Canadian Intraday Data Source?

I use CSI data for EOD Toronto Stock Exchange (TSX) data.
Does anyone know where I could find intraday data for TSX stocks? I’m interested to backtest a few intraday ideas on single stocks using 5 minute bars. Any help greatly appreciated.

@matt though I do not use them personally, you could look at DTN IQ Feed, eSignal, and Interactive Brokers. I am sure there are others.

Thanks - much appreciated! (The couple I looked at are pricey but it seems like there’s not many options for Canadian intraday data.)
