Whether you need to pick your luggage at YYZ is a good question.
If flying US-YYZ-YYC, you need not to, so I would think if continuing international from YYC, there should be no need to pick them up.
But it would be good to obtain confirmation from someone who did this.
In any event, 90 minutes should be doable. If you miss the connection at YYZ, is there (1) another flight direct to NRT or HND that's later, or (2) a flight that lets you catch a YVR-NRT or HND, or (3) another flight to YYC that still aloows fo the connection at YYC?
I assume it's all on a single ticket?
