I can’t think of much. Changing isn’t unprecedented, but you’re also far from alone driving on the left. Off the top of my head: the UK, Ireland, Australia, New Zealand, Hong Kong, India, Pakistan, much of Southern Africa…
Places that have changed within the last 100 years: Sweden, Newfoundland, the rest of Canada ('cept Ontario and Quebec) switched just over 100 years ago.
I looked at 338, and the my riding’s NDP support appears to be crashing. No liberal has done better than 3rd in a generation, it’s always been conservative or NDP #1, conservative or NDP #2, then LPC, then whomever else. The LPC’s polling above the NDP at the moment so I’m somewhat torn.
