He asked government departments and agencies how much they have spent since 2021 on cloud services provided by Amazon, Microsoft and Google, and to identify which of those cloud services cover critical government functions. "Amazon Web Services hosts several mission-critical applications that directly support operational readiness and national security," the response from the Department of National Defence says. National Defence spent $4.57 million on Amazon Web Services, another $8 million on Microsoft services and $835,691 on Google services. Prime Minister Mark Carney has spoken about the idea of building a "sovereign cloud" in Canada. The government spent $247.4 million on services from Amazon, with the vast majority going to Amazon Web Services, and around $22 million on services from Google.
