What exchanges / markets does Yahoo! Finance track when displaying pricing and volume of Canadian investments?

For example, at 2025-09-19 15:07 ET, Yahoo! Finance is showing DXMO.TO Dynamic Active Mining Opportunities ETF with a volume of 82 while BMO Global Asset Management (https://tools.bmogam.com/en/etf/RecentTrades?symbol=XTSE%3ADXMO) showed 10 trades for a volume of 297 from the following exchanges / markets: CHD, CS2, TSE and current bid/ask of $29.29 - $29.47.

Can Yahoo! Finance please provide more coverage of the various exchanges / markets being used to trade Canadian ETFs, CDRs, and other investments to reflect the current market?

Thanks
