This is not actually true. The only advantage Canada has, for Indian immigrants in particular, is a skill-based immigration program that is fast and does not discriminate based on the country that they're from.

Canada allows a lot less family-based immigration than the US. Parent-sponsoring permanent residences are limited to 10,000/year compared to no cap in the US.

Overall it's the opposite. The US places a heavy emphasis on family-based immigration vs Canada that puts most of their emphasis on point-based skilled immigration.

that's been heavily altered in the last few years.

you can still do so, but the application process has changed to a lottery system, where you get pulled and are then your family is invited to apply. wait time may take years and its not a guarantee.
