Don’t they have a “fair use” policy limiting that roaming to a certain period of time?
OpenVPN really isn’t the best (among the popular) VPN choices. It’s relatively difficult to set up and slow in comparison to IPsec, Wireguard or PPTP, which are probably easier to set up as well.
For your use case (watching streams) you don’t need encryption at all. A plain, unencrypted “tunnel” to your Canadian IP will suffice and be preferably due to no encryption overhead negatively affecting performance.
Maybe also a proxy server or even a “Smart DNS” service. There are ones that explicitly advertise your use case - and should be fastest and easiest to set up.
