I am living in eastern Ontario area. Is red cedar mulching good for
this area? For backyard mulching, what may be the best, to prevent
pest and other drawbacks?

Even old leaves works OK to stifle weeds. Hundreds of millions of
years of forests can't be wrong.
On the other hand, I got tired of the wood chip mulch getting old and
turning to fertilizer for the weeds every year, so I've just started
up a test bed with a layer of that spunbonded weed barrier cloth from
home depot and that newfangled recycled tire rubber mulch. I'll let
you know how it works out in a couple of years. It's like $12-15 per
cubic foot, so it better last.
