I have done a lot of driving in Ontario, Quebec and Nova Scotia. Yes, same basic rules apply for Canada.
One thing that is different out east from here is that there are expressways. On those, there is a regular looking freeway with multiple lanes in the center. Then there are two lane highways that run alongside the freeway. At specific intervals, there are off ramps that take you from the freeway to the highway and visa versa. The highways have exits to other roads.
So, if you are going past a city, you stay on the freeway. If you are going to be exiting into the city, you move onto the highway first.
The other thing that is different is that when an onramp merges onto a highway or two lanes merge into one, the white line between them continues until it's off the road. Here, the white line just disappears and the two lanes become one wide lane until shrinking to a single lane. There, the right lane is always identified but it runs off the road as the two become one.
So, it gives a better visual clue that the right hand lane drivers need to merge into the left lane, rather than the left lane merging into the right.
