Indian naan bread with cheese is also a great feast!
I am yet to visit Canada but I believe that the Lebanese community is the largest Arab community in Canada although many Lebanese are actually of Palestinian origin. That might explain the prevalence of Lebanese cuisine. Also most Westerners will like Lebanese cuisine as it is one of the least spicy in the Arab world. Although I like Lebanese cuisine, there are IMO, numerous better Arab cuisines out there. Iraqi, Saudi Arabian, Jordanian, Yemeni, Egyptian, Moroccan etc. to mention a few. However I understand the appeal of Lebanese cuisine for the average Westerner. It's the cuisine that many are most familiar with when Arab cuisine is discussed. It has also great similarity (in many ways) with Southern European cuisines, in particular cuisine from Greece and Southern Italy. That can be said about many Arab cuisines but Lebanese is probably the closest. You also got French influences due to past French presence in Lebanon.
However the more "exotic" Arabic cuisines are IMO better and have much more to offer. After all Lebanon is not the largest country in the world and regional diversity is comparable to its size. A great cuisine though, no doubt about it.
I believe that Indians and South Asians in general would feel much more familiarity with other Arab cuisines than the Lebanese one. For instance the Moroccan, Saudi Arabian, Iraqi, Yemeni, Omani etc. Most of the spices are similar for instance.
