When people immigrate from different countries from around the world, they are making sacrifices. They are losing there families there home and sometimes there memories. One way that people make sure that there religions and cultures stay strong is they keep records of there past such as photos or videos. I know that in aboriginal cultures, the elders will pass on there religions with story telling and songs.
Some aboriginal people might be discouraged to come over to a different country becalms of how they were treated in the past by Canada. Aboriginal people were forced into a new belief system that was considered “White”

Where as some people who come over to Canada could benefit from moving to Canada. Since North American countries have such powerful media influences that could mean that people who were willing to try and expand there culture they could do so by our large media population.
