There is a channel called Fox Sports Racing... Maybe only on Rogers. They broadcast all monster Jam shows at the same time they are released on Fox Sports 1 in the US.
As for the archived episodes, there were a few youtube channels that I've seen with old TV footage with terrible quality.
the 2001 recap show was posted on one channel.
the 2002 series was posted on a different channel.
the 2003 series didn't exist.
2004-2006 and some 2007 episodes were posted all on one channel (dont know if mods allow Youtube links)
2008-2016 TV episodes are nowhere to be found on youtube.
There are some episodes from 2009-2012 on hulu, but I cant watch it in Canada.
