Here (20000km from Canada) on the radio climate specialist says "we don't know for sure if it's climate change at work, models don't agree". My gut feeling is

  The proximal cause of this heatwave is an omega block in the jet stream. Atmospheric models predict that these types of events should be less common as the world warms. At least that is what I was able to read about it a couple of days ago when I was worrying about this same question.

  The problem is that for now, it's still a statistical anomaly, like the snow in Brazil is; it's uncommon, but if it's only a few days, it's going to be a blip on the radar and only a few tenths of a degree in annual statistics. The temperature at the moment is weather; annual and multi-year statistics is climate.

(disclaimer: just being devil's advocate, climate change is real and "freak weather events" are becoming so common now that you can't deny it being a trend and the direct effect of global climate change)
