MCT still showing as 1:10 on expert flyer. Do you have nexus for CBP since you have to do preclearance in YYZ? All my recent domestic AC flights have been delayed by 10-15 minutes on average so that cuts into your margin.
I've done the redeye from YVR to MCO via YYZ before covid and decided even then to take the longer layover. It gave me time to get on the UP and have a nice breakfast/brunch downtown without worry.
