Can my husband and I stay in Thailand for 60 days without a visa by using the 30-day extension rule?

Yes.

Or go to Immigration, pay 1900 baht and get 30 days more,

You won’t need to exit and come back. Your 30

Day visa exemption when you arrive (assuming Canadian passports) is extendable by another 30 days at any immigration office in Thailand for 1900 baht each. Enjoy

You had time to plan a 60 day trip but not time to apply for a visa?

You need to check with your airline to see if they require proof of leaving Thailand within 30 days if you are traveling without a visa. If they require that, they won't let you board your flight unless you can show them a ticket out of Thailand within 30 days of your arrival.

Once you're in Thailand you can apply one time for a 30 day extension at your local immigration office, giving you 60 days total.

The day you arrive is counted as day 1.
