According to Tony Hwang :
Hi,
Speaking of HD(American) and Rona(Canadian, BeaverRevyRona), prices
are often better at HD for identical item.

Often, certainly, but not always.

HD Canada appears to be run somewhat more at "arms length" from the US
parent than is usual for Canadian divisions of US chains. Ie: entirely
different staff hiring practises. Canadian HD employees tend to know
what they're talking about - eg: the guy in the plumbing section is often
a licensed plumber with lots of experience.[+]

By all reports, US HD employees generally don't (and are as bad as the kids
at Canadian Tire).

[+] A plumber told me that many of his licensed plumber friends part time
at HD to fill in the gaps in their contracts...
