Similar situation to yours. When I got married, I told my wife that the bike is off the books, and not for discussion.

Make sure your accidental death insurance is reasonable. ($14/month)
The main concern I have with pending offspring is the "half in, half out" situation where you:
- have less spare time to go riding, don't get the "repetitions" in like you used to when riding every week
- more distractions in life
Both combine to an increased likelihood of just not riding "in the zone" which I think is incredibly dangerous.
I would hesitantly recommend a cool sports car only if you have an interest in doing lapping days/club lapping days/autox/drag racing. If not, having a fast car in flat roads of Toronto would bore the **** out of me. Being on 2 wheels makes it marginally more palatable to get to the twisties outside of GTA. Now if we were talking about Europe or California, this would be a completely different story. For the fella that is contemplating sports cars, definitely stick with the top 3: Miata, BRZ, non-zo6 Corvette. Maybe BMW M3 or 911. Anything else is far too niche, and when you show up at the local lapping/autox day, and you are the only person with that platform, it gets boring even in that competitive landscape. If you compare that to a Miata, there will be 5+ others at any event, and the brotherhood/friendly competition makes it so much more enjoyable--I'd say even more so than riding 2-wheels with friends since you can LEGALLY compete with your friends in addition to the cruise in/out.
If I had a kid show up on my doorstep tomorrow, I think I would store both bikes, get Tesla to get my heart rate up from stoplight to stoplight, and probably pick up a little city scooter or electric dirt bike. Saw one ($4k usd though) from Segway earlier, and that really looks like fun. But the above mention of "nowhere to dirtbike for fun" would certainly make me backpedal that stupidly expensive decision and probably settle for some cheap to insure scooter. Though I bet an electric dirtbike would be fun on regular bicycle trails if that's permitted... Certainly would fit the same use cases as my bike currently: "terrorize the streets and neighborhood parks before 8am, back home by the time the household wakes up"
If I were in Cali, I would 100% get a Tesla. I did 2500km earlier in August over 3 days, $0 for gas, autopilot between LAX to Fresno to Lake Tahoe to Yosemite to Big Sur back down to LAX via PCH. No way I could have enjoyed the twisties if I had to "drive" interstate. Bank your awareness and attention to when the elevation changes with twisties. The only thing that would come close in the GTA would be a MC or something electric 2-wheels on a hitch of a Tesla that would auto-pilot you to/from something cool.
