Does anybody have some experience with these yeasts (Ardennes and Canadian/belgian)?
I pitched at 20 C, maintained that temp for 36 hours until I had a good ferment going and now free-balling up to a max of 25C which I expect them to hit by the moring.
Does that sound like a good temp-profile or is it getting too hot?

I think Mike Neilson and/or JoKing are the right men for this question.
I've brewed with Ardennes and started at 18c and slowly raised to 22c over one week. Results were excellent, yeast character very similar to La Couffe. Not sure whether 25c would be OK but from memory Mike said that 28c is OK for Ardennes.

I'm brewing with Ardennes at the moment, and followed a similar temp profile to yours (maxing at 24), although my OG was a little higher at 1.071. It went gang busters to start with but slowed at about 1.020. From there it's been a crawl to 1.008ish, I'll probably rack it off this weekend. Apparently La Chouffe ferment pretty warm so you should be ok.
I've brewed with the Canadian strain a few times. It doesn't like getting too hot too soon, as it will crash hard and not attenuate fully. It's not the most attenuative strain full stop really. The solution for me was to increase the pitching rate by double and keep it at 19 for a few days (say 50% attenuation) then free ball it up to 25 if need be.
The Ardennes strain is less fussy, and can handle rediculous temps during active fermentation. It just gets fruitier and fruitier. Kinda like that juicy fruit chewing gum... mixed with that old school bubble gum flavour.
