One can run on a moderate conservative platform using evidence and facts.  Unfortunately in the GOP, you had a strong anti-intellectual element take over and unfortunately there seems to be some people north of the border who want to ape the GOP.  Conservatives in most other developed countries (at least the mainstream ones, not the right wing populists) have generally stayed away from this and these types have developed their own separate further right parties like you see popping up in Europe.  Only in the US have they successfully hijacked a mainstream conservative party although in Canada it could happen too.
