You need to be certain of your reasons for doing it. Economically and environmentally, I don’t think, in Alberta, that a heat pump solution will yield substantial benefits.
This article here:

points out that a heat pump relies on electricity, which is a worse GHG contributor than natural gas in Alberta due to coal-fired generation. The article ultimately concludes that its a wash, with heat pumps not substantially contributing to a reduction in GHG.
It’s quite an interesting question overall though, and I’m looking forward to seeing the responses in this thread.
