That's her father I believe coaching her there.
Should be another Tauson/Fernandez finals, hopefully Fernandez wins this time around.

Tennis Canada is pretty strict on their conditions to help financially. Only if they have full control and power over the player will they completely support you financially. They don't want parents to be involved in any of the coaching. I'm guessing this is probably the reason here, the father is very much involved with Leylah's tennis.

Correct me if I'm wrong but Denis Shapovalov's mother is very involved in his career and they pay all his bills ...

Yes correct, but Denis is now a Top 30 player and the rest of the team is made up of Tennis Canada coaches.
When Denis was 16, same age as Leylah, I believe he had a sponsorship for his travel expenses. Denis wasn't part of Tennis Canada as a teenager, wasn't supported financially by them.
