That EOR project isn't in operation yet, the pipeline isn't finished. I think they got financing Q3 2018 and it shouldn't be finished until end of 2019.
Highly doubt it has anything to do with Enhance or their CO2 flood.

The GSC website has this at an approximate depth of 1 km. In that area, it would be well above the target injection site. I have an inkling that this may be an "induced seismic event" but that the injected fluids may have released a fault shallower than the targeted strata.
If true, this may be one of the larger "induced seismic events" in Canada, similar in magnitude one in NE BC in Aug. 17, 2015. A 4.6 earthquake is usually not very impactful but people certainly notice them. The relatively shallow depth of the epicentre would make this even more noticeable. I'm sure that there will be a lot of scrutiny of this for some time.

We had one in the Shuswap Saturday night. Only 2.2 magnitude but it shook our whole house and was felt over the whole region. Earthquakes are crazy.
Was in Tokyo last year. In my hotel room sitting on the bed it started to shake sideways. Thought there was some sort of building construction but then everything started to shutter - windows, picture frames, tv, everything. Ran for the doorway and had to hold on which the building jiggled pretty hard. Ended up being a 5.4. A little freaked, but the locals shrugged their shoulders over it. Happens all the time over there.

I'm surprised it shook the house. When I was in the Philippines we went through a series of earthquakes which generated hundreds of aftershocks. The 3 point aftershocks were more of me thinking I almost felt another quake starting, but not enough to shake the house.

I had a similar experience in the fall in Hong Kong. My friend and I were on the 18th floor and we totally felt it, and needless to say perhaps, we were pretty freaked out. We went down to the lobby and the staff had no idea, and their reaction was basically, "yeah it was an earthquake, but just a little one". The epicenter was far away, and I guess it was minor, but being the one and only time I've experienced one, it was still quite unsettling!

Yeah it was weird. Definitely shook the house but only lasted a few seconds. Emergency crews ‘responded’ right away but they didn’t know to what they were responding. Early speculation was everything from gas explosion to sonic boom. Some lady claimed she saw 4 fighter jets fly past her house (in the dark). Of course conspiracy theories are running wild now.
The Japanese take the high frequency of earthquakes (and typhoons) into consideration when constructing tall buildings. They make them more flexible. I was in Tokyo during a bad typhoon and the hotel was just rocking back and forth slightly.
Never heard of an earthquake in Alberta before. Wow.
Looking at a dataset I have from 2017, I see 10 over magnitude 4 in the past 8 years. There are about 100 over Mag 3 in the past 10 or so years. So not all that rare, though this is the first over 5 I can see.

Looks like it was centred SW or Red Deer, that Clive project is NE of the city if I am not mistaken so highly unlikely the two are related. I agree, the 1km depth is pretty shallow and most wells in this part of Alberta do target deeper formations. I agree with Terradude's initial assessment.
