Two of Canada's biggest internet service providers are preparing to increase their monthly subscriber prices.

Rogers Communications will raise prices for most of its current internet plans by $8 a month, starting Monday.

For its lowest-price plan, there will be a smaller increase of $4 per month a package that delivers speeds of less than 20 megabytes per second.

In April, Bell Canada will increase its internet prices by $5 a month for Ontario customers and by $3 a month for its customers in Quebec.

Bell will also increase internet overage charges to $4 per extra gigabyte, from $3 per gigabyte.

Representatives for both companies said in separate emails that the price adjustments help fund improvements in the reach and capabilities of their networks.
