Canadian car insurance driving to Mexico ?

Hello,
We’re based in Montréal Canada. We got our condo in Zihua in 2018 and we always flew there.
We are getting a new car and I’ve been calling insurance to get some quotations.
I’m thinking of driving to Zihua maybe next fall, or fall 2022, but the 3 quotes I got for now cover only Canada and US, not Mexico.
Do anyone know a Canadian insurance company that cover driving to Mexico, or do we have to subscribe an insurance with a Mexican company?
Any experience to share from fellow Canadians ?
Thank you!
