Used to commute by road bike, 50 ish km total with a bunch of elevation and it was doable, but tiring. Bought an ebike cargo commuter last year and now it's my new "car". I ride everywhere on it and do as many errands on it as possible, as it's convenient, fast, and keeps me in a better headspace. I ride every day to work, rain or shine (no snow), 30 ish KM total. From Vancouver to a suburb along some of the routes you've mentioned, takes me around 30 mins door:door if I'm hustling and if I'm not stopped at lights. I can do it as fast on my road bike but I'd have to ride hard tempo, and would have much less left in the tank at the end of the day for play. It's a no brainer for me to ride, as long as I have access to reasonably separated bike paths. Do it, it's much better than dealing with traffic and all the dickheads on the road.
Having commuted through the city by bike for much of my life, the paths and infrastructure are getting pretty amazing. Wet, rainy, and dark days also mean fewer people on greenways - less to look out for when you're tired, and a much more enjoyable commuting experience. Given this, having the ebike has really made things easier, and has also opened up different paths and parts of the city I would've otherwise not explored. Blah blah blah, I await the ebike haters.
