Canada	conditional	supported
United States	unknown	unknown
Pricing treatment	USD per-user tiers; Google Workspace dependency applies	CAD annual plans; Teams prerequisite and PSTN model apply
Source observations	The official Voice surface publishes Starter, Standard, and Premier prices in USD and identifies Workspace as the base plan dependency.	Microsoft publishes Teams Phone Standard and calling-plan combinations in CAD on annual auto-renewing subscriptions. A separate Teams licence is required; PSTN can use Microsoft Calling Plans, Operator Connect, or Direct Routing.
Open limitations	The cited prices are in USD, including on the Canada-facing research surface. Canada-specific calling, number and messaging limits are not fully verified here. Confirm each required capability.	Budget for the separate Teams prerequisite, Phone licence and chosen PSTN service. This profile does not establish equivalent US pricing or availability.
